Hi everyone, We have one Molly who frankly I think has the shimmies- thrashes about while staying in place, makes exaggerated movements but doesn't swim anywhere. The other day I noticed some white feces. Our other Molly has normal feces but his fins have turned reddish and will swim around for a bit, then lay on his side on the gravel, leaning next to an ornament. What could be bothering our fish? Recommendations for course of action or medications? Please note that we do have a scaleless fish- I know some medications can't be used with them in the water. Our nitrates/nitrites/ammonia levels are all fine. Our pH and hardness is set for the bn pleco we have but we were advised that the mollies, likely being farm raised, would be able to adjust fine to this type of water, plus I'd rather keep the water at the pH and hardness it has coming out of the tap than try to alter it. We've had the mollies for a little over two weeks now. As a newbie, any and all help will be greatly appreciated!
