Hello all newcomers !!!
Starting from today I will post articles about tropical fish.
I hope you enjoy them.

How many tropical fish can I have?
The general rule of thumb is 1 inch of fish per gallon of water. Remember to use the future adult size of your tropical fish when computing the total inches of tropical fish you can have. This rule is pretty silly if you think about it though. Do you think a 20 inch tropical 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.

I just set up my tank and now my tropical fish are dying?
Most likely the tropical fish are suffering from ammonia poisoning. Ammonia poisoning is easily preventable. Avoid adding expensive and less hardy tropical fish until the aquarium has cycled. You can use a substance called zeolite to help absorb ammonia but the best solution is to ensure that your aquarium has cycled and that your tank is not overcrowded. If your tank has not yet completed the nitrogen cycle, you will need to perform frequent water changes to keep the ammonia levels down.

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