i realize this is an older post but how are the little guys doing? i've tried keeping little ones before and i know about the dropping like flies thing. 3 3" babies both times, they lasted less than a month.i'm getting 3 4-6" ones from TFD on Wed. all the ones i had before ate just fine. but just started dying. this time they are going in a 75 with a penguin 330, and a 300 gph canister and NO heater! the tank temp is 68 to 70F and has 2 large bubble wands on standby.Driftwood river stones and hornwort. the thing about the parasites is the last time i had some they were treated with Prazipro as soon as i got them and i still lost them. thinking the temps were too high. probably 76+.these guys are gonna be bigger and well started. Joe (TFD) told me he's had them a few Months and grown them from 2 -2 1/2 ".Sooooo, wish me luck.these guys are as close as i'll ever come to owning a snakehead again,and i just love them! like a snakehead and knife all in one.
