How many fish can you have in a five gallon tank?
We have a small fish tank. We have slowly added more fish. How do I know when we have too many?
how many fish do you have? what kinds of fish? the rule of fish is their full grown size an inch per gallon. so if you have a 5 gallon tank you can get 5 inches of fish (full grown length) Pet stores will have the max size listed on the tank. so for a tetra that grows to 2.5 inches the max number of fish you would want would be 2. Now most people also want an algae eater for their tank. For a tank this small you will only be able to have a snail. common plecos for example grow to 24 inches in 6-8 months needing at least a 24 gallon tank. many Goldfish grow up to 36 inches and are too big for your tank. more fish than this and you are seriously jeopardizing their health and possibly stunting their growth. Also assuming you have all the correct supplies?? filter, chemicals and heater are musts. with 2 2.5 inch fish in your tank you will have to do partial water changes 1/3 of the water 2x a week with more fish than that you are needing daily changings. your best bet is returning/surrendering the extra fish.
Th ratio of fish in a tank is 1" of fish (length wise) to every gallon of water. You have to be careful of how big your tank is, and how big the fish will get when they are full grown. If you have a 5 gallon tank and a fish that will get to be 18" when full grown that fish is too big for the tank. Also keep in mind some fish like betas and gouramis breath from the surface as well as take oxygen from the water, so there is not as much of a problem of overcrowding. Just make sure you keep your tank clean.
Depends on the fish u chose, width of tank- really they say 5-7 should be max
Well it would really depend on the size of the fish but even for 2 beta's (with a divider) the tank would be too small. if the fish are about the size of a beta I wouldn't put more than 2, 3 if you absolutely have to.
It depend on the type of fish, if you change up the scenery every time you add a new fish will help with any aggression or dominate fish.
