Right now I have a 100g community tank with a breeding pair of discus in addition to 5 other discus, 8 angels, a handful of ABN plecos, a large female brown BN pleco, and a couple dozen neon tetras and some rasboras. Then I have my 55g tank, which is currently housing 8 sub adult discus, my breeding pair of rams, a lone female ram, and 3 ABN plecos. I pulled the eggs from this tank to work with them.
I also have a 29g tank with over 100 Endlers and about 20 rams growing out. Then I have a couple of tanks with shrimp that I breed and sell, including a 29g RCS tank, 10g snowball shrimp tank, a 10g yellow shrimp tank, and a 10g CRS/CBS tank. I also have a 10g tank with pretty much nothing in it. I'll be moving the ram fry to that tank eventually. I'll probably be selling off a decent portion of my fish if the rams take off. I am just starting to get them going hopefully if all goes well.
I do PWC's on different tanks on different days. I might spend 10 hours per week messing around with my tanks not including selling stuff.
