Ok as far as compatable fish with an ADF
, YES! My brother has 2 with neons, platies, guppies, endlers, and a snail. Most bettas get along with ADFs well. Just dont pick a particulary nippy fish or a fish that can fit an ADF
in its mouth. Also be sure they are eating as they can be outcompeted for food.
As far as the light goes it depends. If it is a incadescent then probably anubias and anubias alone. If it is a flourescent then there are alot more options. If it is not a flourescent then buy a compact flourescent that matched the wattage and you can grow alot more!
