Help. Horrible sight.
I wrote on Monday about a tiger barb swimming strangely, but then all was better on Tuesday so we joked about constipation. It's been fine but I've just looked in on them all and it looks horrible.
At first I just noticed a very swollen tummy so I wondered whether we had a tummy full of eggs/pooh or something like that going on. (Of course I have no idea if it's the same fish anyway.)
Anyway, it then turned around (it's swimming quite normally and seems happy) and it's belly looked bright red. Thought it may be full of blood (!) and now I'm looking at it again and can't figure out if it looks as if the scales have come off and the skin is very transparent or even it it's a hole ?!?!
What on earth could it be and do I need to get it out of the tank before all the other fish become the same???
Will go do water test now, but wanted to get you quickly if you're out there.
