Thanks to all who helped me on my last thread about the appropriate ph for a ray. Today I went to my lfs and picked up a nice male retic. His disc is approx. 5". I saw him devour bloodworms so thats a good sign. Also, they were only $30 so for aroud here, thats a pretty good deal. I acclimated him in my 10 for about 2 hrs (hope that was good) before adding him to his 90g growout. Now, I'm just wondering if I can get as much input from everyone that has ever kept a ray. I just want to know what all tankmates you've had that worked or didn't work. I'm looking to add some friends. His next home will be a 150, the on to 180 and I'm not sure after that. That should be a couple years down the road. Ideally, I want to get a few more rays, but wanted to take it slow and start with one. The top will consist of a black aro as soon as I can find one. Thanks for your help.
