Ok, I have a few questions here. I am wanting to get a bimac but am wondering if it's ok to keep them in a smaller aquarium, 20 gallons, while they are small. It seems like a 75+ gallon aquarium with LR would make it quite hard to find something with a 3/4" mantle. I know some people put smaller containers inside of larger tanks but already have a 20 gallon set up. How long would a bimac 3/4"-1" last in a 20 before I would need to move it into a large aquarium? Also, does anyone have any actual facts on how bimacs go with soft corals like zoo's, rics, etc? I have heard no, and I have heard it's ok and am not sure what to think.
