I Need Help

[dood]

I know this is a debatable topic,but I believe it gives them a bit of a more natural challenge.I only do this once a week and they seem to like it.I have two suppliers of rosies and feeders I use,and I have to say no feeders have died in their tank for about 3-4 years.Just my $.02 cents worth

wasnt very good to do that with piranah's as they need a cycled tank
but try to do as many water changes as you can to keep them healthy and they should be fine.
