I have a new 55 Gallon I just started, I upgraded from a 40 G Hexagon Tank. I currently have a BGK,3 Platy, a Gourami, a Bristle Nose Pleco, 4 ( 2 of each) random smaller fish, 2 loaches, and a 1 1/2 inch-ish Gar Characin. My gar and BGK have eaten all my small fish as I thought they would and I was wondering what types of fish would work in my tank as I would like to add some more fish that would get eaten and that would get along with my more aggressive fish. ( yes I know I need to have a larger tank, I am upgrading as the fish get bigger). I have 2 bubblers and 2 filters, anything would be of help! Thank you!
