Answer 1

Ryan first off can any advice you get on this one inch of fish malarky because it is just that MALARKY and you cannot use that to gauge your population capability. Please just let your tank be as it is now. Yes increased filtration will help in terms of oxygenation and water chemistry stability, but it's not going to give your fish the physical space they should have. Your fish are going to be just fine in the numbers they have and that's a little on the heavy side for population in a five gallon tank and you should be able to compensate that with your filter, but just let things be. If you want more fish that badly, get a 10 gallon tank or 15 for them. That's not expensive at all, more space and you could mix in a couple cories for substrate cleaning and dazzle up the colors more that way

ADDITION:

I have to say something here. Whoever is thumbing this down is a total idiot ok. All of us here are saying the same thing, so whoever you are that thinks this is ok for him to add on more simply because he has superior filtration, at least have some cahonas get your @$$ in here with your own post and let's have you enlighten us stupid people Einstein. I SWEAR you must have so little self esteem to thumb others down that are right that you need some pyscho analysis. You are a COWARD

Answer 2

Get a bigger tank instead of a bigger filter only. The cardinals and the "blue" tetras (not sure what blue tetras are, I'm assuming it's probably a dyed white skirt, or a colombian) each need to be in groups of about 5+ of their own species to be happy.

If I were you, I'd get a 10 gallon tank with a filter rated for a 20 gallon (or a bigger tank if you can afford it). You can then increase your numbers of each species, and even add a centerpiece fish, such as a dwarf gourami.

Make sure you do weekly water changes of about 25% (with properly conditioned water) because cardinals are very sensitive to water quality.

Answer 3

You're the kid that just sat there while your goldfish died. Why did you guy a huge filter, instead of getting both a bigger fileter and tank. That sounds like an enormous filter for a teeny little tank. I would not get any more fish. With tetras, to be honest you didnt need such a big filter. Goldfish are wasteful and too big for a five gallon, but thats no reason to get a gigantic filter for a teeny tank with small fish. I am sure these fish will be OK, not very ahppy, but OK, as long as you don't get any more.

Answer 4

You are probably at your safe limit already. As for extra filtration, there is only so much filtration you can safely put on a 5 gallon tank. I wouldn't put more than 15 gallon filtration on it max or the speed of the water might be too much for the fish to handle. A 10 gallon filter would be ideal and if you keep a close eye on the water quality and do regular water changes you might be able to add another cardinal tetra to the mix. More fish means more fish waste which means more frequent water changes.

Answer 5

Hey Ryan:
Instead of spending the money on upgrading to a 55 gallon filter, consider upgrading to a 10 or 20 gallon tank and add your extra tetras. Depending on what size your filter is meant for now, you may not even have to upgrade it. Tetras do not put a high bioload out into the aquarium like plecos, goldfish or cichlids.
If you jump onto craigslist.org or ebay and check for sets in your area that are used, I'll bet you find a great deal! I picked up a 40 gallon long with a stand, hoods and lights for under $50!

Answer 6

Yes and no... with a better filtration unit you can over stock a tank, but it's not just a matter of buying a larger filter. A 50 gallon filter would turn the 5 gallon tank into a whirlpool and the fish would die from the stress most likely. To overstock heavily with any real chance of success take lots of planning and careful consideration of the fish choices.

I would say just don't do it, don't even go there.

Answer 7

No.

The tank is too small to add any more fish.

Answer 8

Our pet store recommends no more than one fish per gallon, so you would be at the limit.
