I've had four of these and all have died within 3-4 months. I'm not trying to deter you at all... just sharing my experience. I had three that I grew out from about an inch and one just recently that I bought at 7.5" thinking he would be more durable. Three of them including the big one died from stress. The other was by mistake, which I'll share in a second. These fish were kept in community tanks and I've been told that I should try to keep one in a solitary or pair tank, but I 'm not sure I will try this again... at least not any time soon. The one other that I lost goes like this... I sold all of my big cichlids in like May 2010 and decided to grow out a group of all males in a mixed community (what I still have). I was moving the grow outs from my 56g tank and putting them into the 265g, however I had a 12" wolf fish in the 265g and these were my only two tanks running at the time. I asked my girlfriend to help by holding the wolf fish in the 10" net against the glass of the 265g. The wolf fish was just chilling. So I'm dropping the little guys 3" or so into the 265g on the opposite end of the tank (7' long). My girlfriend is NOT paying attention to the tank and watching TV. I just got the last of the little guys out of the 56g and turn around to put them into the 265 when I notice the wolf fish is not in the net anymore and is chompping down onwhat looks to be my lil Cuban!!! I just don't have any luck with Cubans I guess??? Good luck with yours.
