I thought I had posted this a while back but guess not. I've had these guys for a couple of months now and they are doing spendidly if I must say so myself. I did loose a couple but due to my own negligence. Here's a tip...if you have a powerhead in your tank and it's not running, remove it. Small fishies will find their way into the outlet and get stuck. Anyway, the remaining guys are doing great. So much so that I ordered another group of them along with another species that should be here sometime next week. Ain't she just adorable?
