under it's belly. This was part of a group of 4 which all came from store where they and others were sick with who knows what (now go to China town area where fish are much healthier, steralized water so on). No more buying from stores with dead and sick fish.

These four survived, but noticed now one not swimming with the group, which they do - stick like glue to each other. He was hanging under some plants. Next day with better light, I noticed he had this tubular bulge. They are very flat flat fish, so hard to describe. Not a regular roundish bulge but more like a column due to their particular shape. This is right over his elimination area, which is closer to his front end.

But what grabbed my attention was this reddish area I think near his elimination area (uh hmmm, to be polite)

I quarantined him (thank good they are not that shy and he is fine with a little mirror to keep him 'company'. I treated with parasite meds. I have no idea what it is, as it is not just one string or thread, but seems like a cluster. I feel it is something internal and he may not make it, not eating like the others, kind of goes for food then stops.

Question: Can feeding squashed snails cause bacteria/parasite problems. These snails are extremely small, about 1/4 (really much smaller) flattish reddish snails that are in my prefiltration set up. They are many generational, and I feed them to my fish on occasions. Could they have bugs if they are multi generational?

So not sure what it is, how to treat? Tried to look tonight with little flash light and hard to see he is so small. But area seems inflamed with stuff coming out of poo area although it may be his little frontal fins - just hard to see clearly, but others do not have this. Thanks for any thoughts. Sherry
