I've had my hmdt for a few months and just moved him to 10g. Eventually I decided to get him a friend in an adf. They get along fine, no aggressive behavior (except when I first but the adf in Apollo flared until he realized its just a frog. They like hanging out under the water sprites together (its cute ill post a pic). The only question I have is, does apollo get jealous when I feed the adf? Sometimes when he sees me feed the adf he looses his color and goes of and hides in the plants!? It happend like this, I fed apollo a nls pellet as he's munching I feed the adf some top fin frog bits. The second he sees the adf eat the pellet from my hand he acted like he saw a ghost....then started looking like one! Should I be worried or do anything? Is he jealous since apollo has never seen me care for another animal?
