Just bought retic at lfs. I knew nothing about rays. Now I know little. They told me he wouldn't get larger than 6 inches and that he would be fine in my 125 with Africans and flowerhorns. I dropped $130 on the little guy (4inches) and brought him home. It didn't take long to discover that the lfs didn't know wtf they were talking about. I now plan on him getting 12-16 inches. He did fine in my 125 for first two days till he found convict fry and was attacked by their parents. Once they got a piece of him it was game on for the rest of the cichlids. I hooked a 20g to my 75 and dropped him in there for the time being. As of now, I dunno what I'm gonna do. Either gonna buy another 125 or gonna kick some fish out the door. One thing I do know...... I NEED MORE RAYS! Thinking of having a tank just for rays, cats, and polypterus. Unless that is a bad idea??? What other freshwater rays stay "small"? Are there suppliers near Iowa?
