internal parasites

When I feed my fish, sometimes I'll notice one expel a little white worm. It literally wiggles in the water. I never can tell which fish it is and the worm is quickly eaten by another fish. I've had fish all my life and I've never recalled ever seeing one expel a worm. I've tried Expel-p for...

Hello 👋 My black molly has a strange color poop. Is this normal? He has been pooping clear poops with red tips for the past two days i fed him some peas and flakes.

This is likely a really stupid question, but in the small hours I was thinking about the years I’ve kept Malawi’s successfully (Circa 10 years) I’ve had some minor issues with this batch I’ve started with recently, seemingly an internal parasite issue. I’ve been feeding Thera+ for the past week...

I have a platy who looked stressed for a few days (fins clamped), delivered some fry, then looked even worse after. It became skinny, hunched, uninterested in food, started hiding, and is now being nipped by the other fish. I showed a video of the fish to a fish store who tested my water again...

Hi all, I'm new here.  I acquired three dwarf puffers three days ago and after a bit of reading, found that the vast majority of them come with internal parasites.  However, I noticed that only maybe one out of the ten threads I had read of people treating their sickly puffers, actually ended...
