Types of fish to mix.

I was thinking that when I get my 10 gallon tank that I wanted to add an algae eater in the tank with my 2 bettas but by that time it will be 4 bettas together. Would that be okay or would that be a bad thing? I am just looking at different types of fish to add together without any of them causing each other harm.

It really depends on what algae eater you are talking about. The most common, the plecostomus, can grow to be a foot or more! Obviously not a good fit for your tank. Of course I also want to point out that algae eaters, despite their name, only eat certain types of algae, which might not be the type that grows in your tank, and that they often need to be fed their own food, algae wafers. Bettas frequently try to eat these and might become bloated if they do so. So if you want an algae eater because they are cute looking, it could possibly work out, but if you want one because you want it to eat algae for you and keep your tank clean, you simply won't find a fish that is a good fit. :)

I hear Nerite snails are really good at eating algae, if you're having an algae problem.
