I decided my new room needs a little more life in it (literally, apparently), so I've purchased a 40-gallon fish tank. It's sitting there, completely empty, waiting to be filled... with plants, rocks, fish, filter, etc. Any recommendations on what types of fish to purchase, how many to buy, etc.? I know algae eaters are always a good investment. I love more tropical fish, but am on a somewhat limited budget (trying to stay between $100-200).

Peace,
Dezign

don't buy algae eaters, get some good catfish, plecostomus are ugly , but they are the best glass cleaners and let agressive than algae eaters

wait 3 weeks after you fill it before buying any fish, let the tank get through the main part of the nitrogen cycle before you put the fish in

a rule of thumb for the number of fish

1 inch of fish per gallon of water (adult size, not when you buy them), so if you have a 40 gallon tank, you could get eight 5 inch fish , or ten 4 inch fish, but that is their adult size, not the size when you buy them, so do some research as to how big they will get when grown

over populated tanks produce too much waste, this leads to killing your fish, don't overpopulate your tank

don't over feed, every new fish owner loves to watch their fish eat, but over feeding will lead to rotting food on the bottom , which leads to high ammonia productions, and then your fish die, that is bad

good luck and have fun! :)

FoBoT gave some good advice. Most people just put water in the tank and go out right away and buy some fish. DON'T DO IT!! They'll die and you'll get frustrated. If you want to try some live plants Amazon swords and Java ferns are always good ones to start out with. For my fish recommendation, I say get a couple udside-down catfish. They'll never bother your other fish, and they swim around on their backs. They even have reversed coloration. Very cool. You can read about them here. Good luck.

Cory Cats (I like Schultzis...kinda zebra looking)
Pleco's
Agelica Cats
Congo Tetras
Kuhli (sp?) Loaches
Flame Gouramis
Glass Cats (AWESOME FISH)
Blue Discus
Clown Loaches
Lake Kutubu Rainbows
Pakistan Loaches
Silver Sharks
Zebra Danios

Those should all be good community fish for a tank that size, and none too expensive.

That Java Fern can grow like crazy! I went on vacation once and let my roomate take care of my tank...when I came back it looked like a swamp!!! :)

I wasn't aware algae eaters were over-agressive... but thank you so much for the info. I've never heard of plecostomus before, but...

wait 3 weeks after you fill it before buying any fish, let the tank get through the main part of the nitrogen cycle before you put the fish in
...it appears I have 3 weeks to learn. :)

1 inch of fish per gallon of water (adult size, not when you buy them), so if you have a 40 gallon tank, you could get eight 5 inch fish , or ten 4 inch fish, but that is their adult size, not the size when you buy them, so do some research as to how big they will get when grown
I think I'll go for a mix of small/big fish... time to do more research so I'll know which species get along best.

don't over feed, every new fish owner loves to watch their fish eat, but over feeding will lead to rotting food on the bottom , which leads to high ammonia productions, and then your fish die, that is bad
Easier said than done... they are cute when they eat, but you're right. I suppose it's better to slightly underfeed than overfeed? Thanks again for all your help... I really appreciate it. Do you have any fish of your own?

Peace,

upside down catfish are awesome, very entertaining, easy to keep, not agressive, they are a good choice

Evadman - Good grief! Do you have a super filter?

lirion - Amazon swords and Java ferns... got it. The catfish you described sound cool, I'm going to check out the link now...

werk - I think I'm going to print out this thread after work and take it to the pet store... just to see what all of these look like. Much more fun swimming around live than in still images online... thanks for the recommendations!

XZeroII- :p

Peace (out to look at upside down catfish),

Hi there!

My father has a 60 gallon tank. It is now its own biosphere and he never has to clean it! Real plants help that of course.

Anyhow, plecostomus are probably the most important thing to start with for sure. They usually stay hidden and if I were that ugly, I would too! :) They do their jobs very well.

Loaches (sp?) are great too. They are white and orange stripped and help keep the tank clean.

Remember to fill the tank first and let it stand for one week before filling it! :)

Good luck...

I have a number of tanks.

My fav fish are probably my Clown Loaches. Make sure you get at least 4 of them - they need a group to thrive and are real fun to watch.

Don't start with them, however - get 5 or 6 small, cheap fish to cycle your tank. (2-5 weeks) If you buy a water testing kit, you can see when your tank has completed cycling. Ammonia level goes down to 0 first, then then Nitrite level goes down to 0, then you are ready to add more fish. Don't worry if a few of your starter fish die - this is common when cycling the tank - some fish just can't stand the ammonia and nitrite spike.

i would also go with smaller fish...

Small, Bright, and cool looking fish often attract more attention...

Also offset it with a few bigger ones...

Good Luck, and hope the tank turns out nice :D

:p

Design: They are all babies, and yes, I change the filter often. Very often :)

Back when we had a fish tank, the algae eaters, scum suckers, plecostomus, whatever you call them just couldn't keep up with "production". Cleanup eventually became too much of a nuisance as the fish got larger. Maybe overfeeding was a contributing factor as well.

Of course, I didn't have the combined knowledge of ATOT to consult with either. ;P

IMO the advice so far has been shady at best. I guess thats what happens when you ask about aquaria in a computer forums.

Go check out www.aquariacentral.com instead. They have a great fish keeping forum over there, and trust me, you will get a lot better advice.

Its not that anythings been super wrong here, just more like incomplete. Leaving a tank with water for 3 weeks will do nothing for your nitrogen cycle. Go over their and tell them your a newb and tell them what you just told us. I'm littleprince over their as well.

Hypostomus plecostomus is famous for its ability to keep the aquarium sparkling clean

Wow, I always thought those were just those "algae eaters". I dont' know jack about fish, but my dad ai a big fish nut and he has two of those guys in the tank (I don't know how big), and it remains pretty darn clean. He usually buys each fish in pairs... All the fish have been living for several years now so I'm guessing hes pretty good at it. :p

We also have a Koi pond outside.

I've got over a 100 tanks from 5 - 300 gallons. My advice to you is to go to the library and check out some books on aquarium keeping. It seems that you have some experience with aquariums so you should not have a problem. If you want plants, I highly suggest this web site : The Krib a great resource for planted tanks (it's a bit tricky for beginners to keep a successful planted tank).

As for clean up crew........ I like Otto Cats (small algea eaters) and Corydoras catfish (I like thier personality). Also don't buy lots of fish at once. I suggest you get some Ottos & Corys along with some schooling fish (like tetras) and let the biological filter get established.

For cheap equipment try these sites:

Pet Warehouse

That Pet Place

ps. What kind of equipment will you be running?


Cheers,
Aquaman

THE ONE INCH PER GALLON RULE IS A MYTH!
It works for small fish, but once you get to bigger fish, say 3" plus, this rule no longer applies. The rule has to due with how much bi-product the fish give off. Clearly, a 4" fish like a Rosy Barb, give off way more ammonia than a 4 - 1" fish. If you get all small fish, under 2", then the rule is fine. Still don' beleive me? Would you put a 40" fish in a 40 gallon tank? I wouldn't even put an 10" in a 40 gallon tank on it's own. Just have to displell this myth.

To start, decorate you tank however you want, wioth everything but fish. Do fishless cycling of the tank. A google search will tell you about this. letting a tank "sit" for 3 weeks does nothing. You need to monitor chemical balances in the tank daily while adding pure ammonia (ammonia bought at hte grocery store is fine, just make sure it is 100% ammonia). Get a chemical test kit that measires ammonia, ph, nitrite and nitrate. "The big four"

As for fish, there is one 'friendly" kind of algae eater, but it's name escapes me right now. You LFS(local fish store) probably wouldn't have it anyways. When I was looking for fish locally, they were notto be found anywhere.

Other adivce. Do not buy from chains! The people there don't know anything. Only buy from mom 'n' pop shops. They tend to know more and take better care of their fish, meaning you'll get healthier fish.

Also, when choosing fish, make sure they are healthy. learn about things like ick and fin rot. Two common problems. Don't buy fish in the same tank as these.

Feeding: Only feed your fish what they can eat in three minutes. Feed once or twice a day. Once you've had them a while, you can leave them for 7-10 days with out feeding them. They'll be fine.

When you start stocking your tank, do not get all the fish all at once. maybe start with a pleco and a small school. Then add more, maybe weekly for a month till it's stocked. This will allow for the tanks biological filter to adjust to the increasing load over time.

Algae eaters: Algae eaters like the slime on the bodies of other fish. The slime is a protective coat, so the algae eaters essentially kill other fish. If you get them, you have to be careful to get other fish that are comaptable.

Filtering. There is no such thing as too much filtering. When in dobut, spend the extra $5 for that bigger filter.

While fishless cycling is occuring, now is a good time to go to the store and look at fish. Let us know what you want to get.

PM me if you need more help. I'm an aquarist, not the best, but it is a hobby of mine. Other people here also seem knowledgable.

I suggest you start with a Pleco and a school of about 6 tetras. What ever you like visually. Move on from there.
