my friend had a 29 gallon tank with like 4 chiclids in it all under like 4" and a pleco. he was good to them for a while then one day he got tired of it and didnt feed them or turn on the light for like 3 months he completely gave up on them. when i went over to his house by the 3rd month and i noticed his tank was all messed up with algae. i turned on the light to only find 1 fish left eating the remains of the pleco and it was all haggard lookin. so i rescued him and took him to my 55 gallon tank with like 6 other fish and they are all really young hes the biggest. but he is always scared and puts his face in the corner and doesnt eat. how do i get him to eat and more social.
