Well if you have too many for the tank space they may start to starve to death because they cannot find enough food. I supplement mine with algae pellets a couple times a week just to be sure they are getting enough nutrition.

What size is your tank? And how many do you have? If you go to J&L Aquatics website, they have recommendations as to how many per gallon, etc. they recommend. You really gotta check out their website. Most comprehensive sale site I have ever seen.

I hope that helps!
