No ich, I'm not sure what it was. I assumed it was a parasite and treated as such.its been a little hectic for me so I would have to say the treatment was poor at best, its turning for the better though. When I first got them 2 were eating, 2 weren't. Of the 2 that were the largest is now prob 4.5" and is a giant bully to the smaller one which is around 3-3.5". These are total estimates. But yea I recently read some other threads saying how their new Heros curare were also not eating when they were first purchased which is an interesting coincidence if nothing else. Definitely grab some though. If I could go back in time I would have bought 8.
