We have a 40 gal aquarium in which we have 6 tiger barbs and 2 tiger loaches (all small at the moment), 1 red tail shark, dinosaur eel, and a talking catfish. We want to combine another tank with this one, it has 7 neons (small), 1 black skirt tetra, sucker fish, cherry barb, and pangio oblonga loache (I believe that is what it is called). Would it be possible to combine these two tanks without anyone getting eaten? The bigger tank is heavily planted with a lot of hiding spaces. We could move to a bigger tank if needed. I know the dinosaur eel will eat anything it can get into its mouth, but it is a small one right now. The catfish spends most to the day hiding in a log.
