Got another tank from a buddy of mine so I set up a red cherry shrimp tank its 55gal I added a few plants and moved a few fish from my other tank before they got eatn into this new tank. I have 7 cory cats one placeo one giant filter shrimp and 6 fancy guppies. Is this already to many fish for the tank? I wanted to get a few more schooling fish but I dont want to overload the tank
