Joined the forum for a bit of help with my Dwarf Monty. Iv had him 4 years so isnt a young fish and he's tough as old boots. Moved tanks 3 times, survived a tank crash, survived a cycle etc. But I noticed something today, admittedly I have never kept an eye on his poop over the last 4 years, but today I noticed he is pooping what look like undigested bloodworm. So its long, easily the size of the fish, slightly red/brown and in places looks like rope.
Im thinking Internal Parasites. I just want to make sure as he lives with a breeding ramshorn population that then feed my GSP's and Figure 8s in another tank and I believe any medication will kill them?
His current tank is relatively new as he threw a paddy when he decided that he must kill the figure of 8 he was sharing it with, the tank was 130L so a bit overkill for a dwarf. The tank he is in has been running 6 weeks, fully cycled with readings at 0 except for a small amount of nitrates. If you wonder how I can claim fully cycled after 6 weeks it was set up with existing media, water, decorations etc and supported with stability for a short while until readings settled. Water is a 20% change each week.
He displays no other symptoms, no change in behaviour etc. Still eats like a monster, swims about ok, no concave belly. so could just be me being paranoid, but i'm attached to the little guy. Could over feeding cause this if not IP?
I have attached some pics:




It must be mentioned the OTOS pooped white string a few days back and I put that down to them unable to find food in a recently established tank. There is no algae.
