Possible Maybe A Trouble

[Big_eyes]

I have 10 rummy nose tetra's in my 200 litre tank. I did a 40% water change last night in my attempts to clear the sand of my plecs poops. I've turned on the lights today and some have a wierd enlarged belly. Not the whole belly though, more like they've swallowed a really small and really heavy stone.

All fish behaviour is fine and normal. All tetras still shoaling together, water stats fine, no erraticness, no new changes or additions to the tank and only unusual difference is that I dropped an algae wafer in today to see if my plecwould be interested seeing as he's ate nothing but algea for three weeks.

Feed some shelled peas.
What does it look like when the fish go to the toilet.
Does it look like a hard lump near the bloated area.
Is an anus enlarged or red and inflamed.
Are scales lifting in the bloated area.

Hiya, things seem fine today. All lumps have gone down and they seem typically normal. Must of just overindulged in their stealing of the plecs algae wafer

I'll let 'em off seeing as it's christmas.
