Hey all,

I came home a little while ago only to see my tank is flooding with microscopic white worms sticking to the side of the tank and crawling around or swimming freely in my tank. I am 100% sure they are worms because they are crawling on the side of the tank. They are around 2mm long and I'm sure this is why my fish have been getting sick recently. I currently have 60% of the water changed and am planning on doing a 100% with scrubbing, but for the items in my tank like a sponge filter and my hang-on filters, what is the best way to kill these parasites? Hot water? Chemicals? Any help would be greatly appreciated.
 
I'm sure you'll read it but if that's what it is they are harmless and due to over feeding or food left in the tank that hasn't been eaten. Pops up in my tank from time to time no biggie.
 
I don't think that's what these worms are. These are white, around a millimeter to half a centimeter longm and are ALL OVER the inside of the tank. My male FH has gotten sick once to the point of almost death but I saved him, and now he's sick again, a week after being treated. Since these worms have popped up, my fish has had diarrhea poop and lots of white in the poop as well.

If you think they're harmless, then no problem but no matter how much of the epsom solution I am giving my FH, he's not getting any better so I thought these might be the cause.
 
With parasites it's usually the ones you don't see that are the problem. Internal parasites could be what is making your flowerhorn sick and if that is the case you should try to treat with Epsom salt internally. If that doesn't work you may need to step up to metronidazole. What are your water parameters?

I'm sure its internal but didn't know if these had anything to do with that.

I have tried epsom for 4 days on this guy and nothing yet, same as last time. I had to force epsom solution into his mouth to cure.

My water parameters are gonna have to wait until tomorrow unfortunately because I need new equipment. Right now my tank is 95% empty and i'm about to take it to the bathtub and scrub it and wash with very hot water. I also cleaned my filters and other things in my tank. I'll get back tomorrow after I get the parameters set up.
 
I had similiar situation and I believe I have the harmless ones from feeding to much. The bloom was big a few wks back not so much now. They're ugly all on the glass but you'd have to clean and get almost all of them out, even filters. That's why I decided just to deal with them, sometimes I can see where they're crawled bc of the eaten algae tracks. I didn't notice them till I added my 80% treated driftwood. Gluck

Usualy caused from over feeding or not effectively cleaning up left over food. Don't feed your fish for a few days, and when you do, cut down the feeding to about half of what you were doing before. If you have gravel or some type of substrate, use a gravel pump to give it a good clean. Wait about a week, then give your filters a clean (not too much as you'll loose the beneficial bacteria).

You can try adding a little aquarium salt and raising the temp, most worm like creatures don't like that combo and will perish in time.

Nematodes! Hideous looking huh... thats ok. I got them once from overfeeding... added copper to the water after vacuuming the gravel and doing a 50% water change and tah dah! Gone.
