I'm planning to upgrade my 90 to a 125 sometime soon. I have 5 blue dolphins growing out in a 50 with 2 venestus. I would like to have a peacock hap tank with the main focus on some large dolphins. I would like a few other peaceful haps or peacocks to go in as well. I would like breeding so no cross breeding wanted. So fish I would like to breed would be blue dolphin, Taiwan reef, and maybe one other species that wouldn't cross breed, peacock or hap. I currently have a single male juvi taiwan reef, along with 3 hap 44 red fin. 1m 2f. Male is currently not dominant hopefully will change after I remove most my other fish. I would like nice color contrast but also keep it peaceful. Also if you can recommend some good bottom feeders that wouldn't complicate the spawning. I will be getting all juvis so I have time to grow out in my 50 and 90 before I get a 6ft. I actually wasn't interested in this until 2 pairs of convicts I was given just spawned and I now have about 100 fry swimming around in my 90. I love it. I should add, my blue dolphins are around 2 inches, my Taiwan reef 2.5 just starting to get blue on his face, and my hap 44 are 4-4.5 but I don't know if I will use them in this tank.
