I was thinking about taking the gravel out of my 25 gallon aquarium and replacing it with pool filter sand and putting the small brackish flounder and bumblebee gobbie in the tank. I at present time have some baby mollies, ghost shrimp and a small bristlenose in the tank, will probably put these in my peacock eel tank.
Just wanted to know besides having the gobies and flounder are there any other good fish to put in tank besides mollies? The tank has been set up since May so it has a well seeded filtration system.
