I've been feeding occasional ghost shrimp to my ray and after getting tired of buying something others are successfully breeding, I'm giving it a shot! I have serious doubts that I could successfully breed ghosts, but I've read that red cherry are much easier. So I took out all of the fish from my 10 gallon and put them in the 120. I ordered 20 red cherries for $26 shipped from ebay. I got them today and I'm happy they all are healthy and alive in the tank, but man, they are juvenile. Small little guys. Its going to take some time till any magic happens. Any way, there are 20 cherries, and I have 12 ghost shrimp in there too that I won't use as feeders, I'll give them a chance to breed too. I have a small penguin 100 filter on the tank but I'm not too concerned, the suction is not all that strong. So here is a pic of the tank. Stay tuned and I'll make updates and tell you how things work for me.
