One proven pair and the Denison Barbs. You could get 4 small EBJD to growout and once 2 paired off then get rid of the 2 others. Tbh your aquarium is not large enough for both EBJ and the EBA.
Okay, thx a lot for your input.
Denison barb is my favorite fish all the time, I had 50 of them in my 250 gallon. How many can I put with the ebjd in long term? I'm planning to move some of mine to the JDs tank, and all of them are 8-10 cm long.
