I'm setting up a new tank 84x30x24 and am considering adding a biota regal Angel as the only new addition.I have no experience with Angels except dwarfs. What are your thoughts on this area in my sump as a grow out tank? About 18g volume full of mature live rock with some sponge and bunch of little critters. The tank on the sump is mature 8 years old. I figure it's probably way better than a sterile tank with PVC. I have the ability to feed multiple times a day and extra food will Just flow over the baffle into the overflow chamber and up to the display. Flow is from a manifold on the return and can be turned down as low as needed. I think it's a good idea but since I have not kept Angels I want to make sure I'm not missing something. I would remove the mesh bags of media so no fins get snagged on them. Thoughts?
