Hi I'm new to the whole aquarium jig and I got two dalmatian mollies yesterday. (The guy at the LFS
said I should get them in pairs.) anywho, one seems way fatter than the other and she stays up in the corner of my tank hiding behind the filter bubbles most the time. && the skinnier of the two looks like she/he [I think it's a she] has a hunchback and likes to hover low, really close to the gravel. Can anyone tell me what's wrong with my new loves? If in fact anything is wrong? or am I just worrying too much?
