I purchased a JD last weekend. He's about 2" and in my rushed excitement, put him in my 180 gallon with fish 2-3 times his size: GT, Sevrums, Tin Foil Barbs, Parrot Fish, 4" Firemouth and a Malawi Eyebiter. All fish are compatable with each other, but I notice the Eyebiter was following the JD closely. Presently, the JD is hiding in a tree trunk and doesn't come out. Should I leave the JD in the aquarium, or take him out and allow him to grow before returning him to the 180 gallon? Perhaps the JD is getting use to its new home and because of its defensive nature, it would be fine to leave him? The 4" Firemouth behaved the same when I brought him home and it took about a week before "coming out". He now swims with the others. Thanks.
