I'm hoping the 18 fish in your 10 gallon tank are VERY small. Usually, the rule of thumb is, one inch of fish per gallon of water, taking into account the MATURE size of the fish. Of course, this rule can be stretched if you have a more-than-adequate filter, and extra aeration. in your tank, you should not be keeping fish that will grow larger than 1 inch when they are fully grown.

As an addendum, I can add that it is a good idea to have fish that fill all 3 areas of your tank, i.e. some of them are top swimmers; some of them are mid swimmers; and the remainder are bottom swimmers. That way, you are utilizing all the space in your aquarium.

I had put my betta in the 25 gallon aquarium with some black skirt tetras small cory catfish and a pleco. The tetras did not go after his fins, and if they got too close he would 'start' after them and they would swim away quickly and he did not pursue, therefore all was peaceful. The betta would sit at the bottom, under the log with the pleco, and neither of those two bothered each other either. Just don't put your betta in with fish that are semi-aggressive, or other fish that have long colourful fins (such as male guppies).
