k, I'll try the Geo cichlid again this weekend when I"m off and we're getting the next snow storm...when I can keep guard and watch. I don't know about the blood parrots and the polypterus though-blood parrots were just pecking away...poly was doing his death roll move towards the eyes. Only one other time I saw him doing that and was to an old arowana we had, who committed suicide a couple years ago. I can go through and list my stock here of ALL the tanks, but I doubt they will be compatible with the ray or compatible with the tank/bioload. I've an old oscar who never bothered anyone, never ate live food even when offered to her, and was introduced to the ray in the 125g. She just stared downward at the ray...like what the bleep is that thing with eyeballs looking at me??? But, the oscar never went over to the ray. However, the tank cannot handle the waste those 2 would put out. I told hubby I'm preparing myself to just maintain 6 tanks, currently set up 265, 125, 75, 54 corner bow front, 20, 5. That's all, at least until we build and combine. I will try the geo again. I do have a tiny pleco of some sort and a tiny whiptail, but the ray would surely eat them both. Same goes for my clown loaches. They're too small.
