    Molly lethargic and losing weight

    Hello all, So I have a 29g tank and I’ve noticed the last few weeks one of my mollies has been getting lethargic and looks quite a bit skinner compared to the other lyretail mollies I have. It’s looked skinny since I got it but seems to be getting worse. She was eating fine but today when I...

    Pregnant or something else?

    I’m out of town at the moment and have a friend taking care of my fish, my female silver Molly was normal size when I left and now she is huge. Not sure if it’s just pregnancy or something else. Any help would be appreciated.

    Need help figuring out if fish are platys or mollies

    Hello. I purchased some fish today that were labeled as platys but now that I see them in the tank I'm not sure if they are platys or mollies, especially the one in the second photo. Can anyone help me identify them? Thank you.

    Very pregnant molly!

    Hey y’all! I consider myself pretty knowledgeable when it comes to tank things and what I lack knowledge on, Google to the rescue. But this one has me all sorts of confused. I “adopted” this Molly 3 months ago. My local fish store has a “Kae Tank” that he puts fish in that he can’t sell for...

    Odd molly fish behavior

    Hi, I recently bought some new fish for my aquarium a few days ago. They are 3 mollies and 2 guppies. Yesterday I noticed that a female Molly was acting strange, going up and down the tank and then staying at the bottom of the tank. I did a water change and tested the water and all levels were...

I will attach an image of her condition; the back of her dorsal fin also looks a little strange. The rest of my fish are healthy. I have a 10...

    So I was browsing the marketplace yesterday and came upon an ad for free fish tanks. I, of course, hopped on it. Just got home after picking it up and setting it up. It turns out, she still had the fish, but would have no tanknonce I left with the last one. She offered the fish as well. I...

    Are these Muppies or just XL Guppies?

    So a friend close to me bought some tanks that came with fish, which he didn't want. I said I would take them off his hands. Ot was a mixed lot of neon tetra and supposedly guppies, but two of these female are absolutely huge. I suspect they are actually a crossbreed, and therefore infertile...
