The Acestro's are easily spooked by lights being turned on/off, and rapid movement so be careful. I had one jump 6" straight up and out of my tan at night. I still miss that guy, but I have a new one now, not the spotted or red cachorro, but he doesn't have a stripe either. I haven't seen any like him before, he was listed as 'peruvian'. This guy will only eat at night, but other than that he's pretty cool. I'd say they seem to respond better to pH of 6.5-6.8, and temps a little over 80, IMO. Also, floating plants or some sort of cover from above really helps make them feel comfortable. Good luck with it!
