I have a mating pair of two fals percs in a 12 gal
tank with a small peppermint shrimp and a hermit crab that is so small sometimes I lose him in the gravel. They're still babies (about 3/4" long) so they haven't reached a maturity in which they are male or female. Most of the time they tend to get along fairly well. They play together often, but sometimes if one touches the other, then it will go to a 45 degree angle and quiver for a second or two. Is this normal? If not, what can I do to help?
Also, they are still at an age where the food is difficult to give them. I'm not really sure what to do because if I give them the small pellets the fish store gave me, they may get one out of ten. If they do get that one sometimes they tend to spit it out, because it is too big. I also have flakes which I have crushed to try to help, but often they ignore the flakes. I feel like my fish aren't getting enough and my bowl is going to get really dirty really fast.
Thanks so much!
