I have a 75 gallon tank that has been running for a few months and I was thinking about having a monster tank. And I need help for stocking the tank, I really like Oscars/SA cichilds,gars,eels and large catfish and I also currently have a syndosis catfish in my tank i also want to have some other inhabitants other than fish like lobsters,African Clawed Frog, Axolotl,big snails and posslibly turtles any ideas?
