Hmm, thank you everyone! & the one has quite a bit of weight but a new injury & is housed seperatly now. The other I feed either ghost shrimp or bloodworms daily, he/she is the aggressive one and is definitely not afraid to eat! The heftyone one wont eat anything besides bloodworms, and wont eat at all at the moment. Im in the process of cycling their new tank, it has nice large rocks, is colder, etc. The skinny guy is still with the fish actually seems pretty happy. He chases fish all day and is always eager to come to the surface and eat, and actually (oddly enough) seems to like my hands and will crawl onto my arm if its in the tank. Im glad i finally know theyre of the warty type, no wo inder the one is such a brat! They have plenty of hiding spots all over the tank, ive even added more now.
