What size tank and what are the other fish in the tank?
ADFs like their own kind for company, but there are some fish that can work out well. Clown plecos, otos, amano shrimp, possibly bamboo shrimp if the tank is large enough. I have my 6 ADFs in a 15 gal with 2 clown plecos and a couple of apple snails. I have to replace 90% of the water weekly because they all poop way too much. But they get along well. ADFs like a slow current and a pond-like setting. Their favorite food is frozen bloodworms. Mine also eat frog bites for aquatic frogs, live Grindal worms and they will eat frozen adult brine shrimp and mosquito larvae but less enthusiastic. Problem with these guys is that they are slow eaters. With a lot of fish in the tank they may not get their share of the food. Make sure you put in on the gravel and right in front of them.
