Optimum Temperature for Tropical Fish Aquarium

Tropical Fish and Aquarium Questions

How many tropical fish can I have?
The often stated general rule of thumb (don't stock your tank using this rule!) is 1 inch of fish per gallon of water. Remember to use the future adult size of your fish when computing the total inches of fish you can have. This rule is pretty silly if you think about it though. Do you think a 20 inch fish would be comfortable in a 20 gallon tank? A better rule would be 1 inch of fish per 2 or 3 gallons of water. Avoid the temptation to overcrowd your tank. If you do overcrowd the tank you will need to perform maintenance more often and you risk the health of the fish you are keeping!

Can I add tropical fish right away?
You can, but this is not the humane way to cycle your aquarium. There are products on the market that can speed up the aquarium cycling process. If you do decide to use fish to cycle the tank, try to use some of the hardier fish such as zebra danios or cherry barbs. Please read about the Nitrogen cycle.

I just set up my tank and now my tropical fish are dying?
Most likely the tropical fish are suffering from ammonia poisoning. Please read about the Nitrogen cycle.

Can I use tap water to fill my tank?
Maybe - first test for chlorine and/or chloramine. Most likely you will have these chemicals in your water and you will need to remove or neutralize them before adding water to your tank.

How often should I change the water?
It depends on how many fish you have and the quality of your filtration system. In lightly stocked tanks, I would recommend changing 10 percent of the water once a week. You could probably get by with vacuuming the gravel once every two weeks depending on the population of your tank. Heavier stocked tanks will need larger (25% or more) weekly water changes and gravel vaccuming.

How often should I feed my tropical fish?
It is best to give your fish two or three small feedings per day. Only give an amount of food that the fish can eat in 2 minutes or less.

What are some good tropical fish for beginners?
There are a few species that are particularly hardy and that can tolerate some of the mistakes that a beginner may make. Check out the Good First Fish page for more information.
