I'm keeping my ram, angel, and cories. I'm down to 3 harleys and trying to decide whether to beef up their school again or to remove them. Also, I have 1 mature female platy and 2 young males. She seems to be tolerating them OK so far, but I need to at least exchange a male for a female. I'm thinking of maybe removing the platies and the harleys and trying something new. I want to keep the ram and the angel happy and have some middle to upper tank action. Thought and opinions?
