Gulper catfish and stingray?

[giar]

Sup folks,

Currently i have my 15cm gulper in the clean water chamber of my sump. It is quiet big, 40cm x 60cm cross section area. The water level is typically 40cm tall.

Im thinking to move my 20cm BD ray with the gulper temporarily until he gains some weight and a bit bigger to compete for food with the other rays in the main display tank.

Currently he is the smallest among my other rays and he always get the least food.

Would this be a good or bad idea?

Here is the pic of my clean water chamber to get u the idea how big it is, even for the gulper itself lol

Sounds like a bad idea to me. How big is the pump? I’d be a bit worried of ray getting sucked to it. 20cm should be ok with others or if not put I divider in.
