Hey,
I have a irritating brackish water fish( mono angel) in a marine aquarium it is perfectly happy, but however i want to get some shrimp but it eats them, we are starting a marine fish only aquarium and want to put it in that tank, but how do you catch because as soon as the lights go off it disappears. and it swims really fast and we have a reef tank and we dont want to move the corals around plz help
thanx
