Ok so here is my dilema...I have a 120 (48x24x24) and a 55 and a 125 that I am picking up in about 2 weeks. In the 55 I have four rpb's ranging from about 6 inches to about 10 inches and a twelve inch pleco. They are all going into the 125. In the 120 I have three 9-11 inch needle fish, one 6-7 inch hoplo, one 5 inch rainbow shark, one 7 inch common pleco, one 5 inch silver arrow, one 6 inch florida gar, one 5 inch clown knife fish, one 4 inch id shark, one 3 inch cray fish, one 5 inch blue cray fish, and one 5 inch fresh water prawn. Here in the next month or so I am going to be buying a 250-350 gallon tank and moving the gar, knife fish, arrow, id shark, and prolly the blue cray fish to the bigger tank. Now, here is where this stocking thread differs from others. What should I put back in the 120? I have never really been into cichlids so none of them, most catfish would get too big for a 120, no pirahna since I already have some. My only ideas so far are 2-3 more needle fish (already have a breeding pair kinda would like more), or more crustaceans. Other than that I am completey stumped. I have looked through a lot of stocking threads and haven't seen anyone that keeps anything with needle fish so I'm not sure as to what wouldn't be compatable. Even though I said no cichlids and catfish I am open minded to anything that could stay in there for life, while keeping the needle fish in mind. (Don't want anything to kill them)
