Black Neon Tetra

Managed to get a decent shot (eventually) of one of my latest isolation box residents 

Good piccie..... nice fish.

They are indeed doing well.  The one I snapped was at the time suffering with a case of "long poo", which cleared up within a day.  Probably ate too much, so I've cut the level down a bit.  The other residents haven't been showing similar symptoms, so likely just a isolated incident.

It's an affliction that is quite commonly caused by the fish eating too much too quickly, or if they suffer from a bit of constipation, wrong type of food. There are more sinister reasons, such as internal parasites, but I had no reason to suspect this was the case.  I had popped in some squished pea, but nobody touched them.  I cut down the level of food as a precaution and waited a day.  Any longer than that and I would have been worried, but as it was everything cleared up nicely.

Ok.... I think I have a fishy poo problem reading these comments. I have no idea what fish poo normally looks like never having fish before, and since my fish have always had poo like this I assumed it was normal.... Going to post over in Fish Health too, but if my fish fit these descriptions what should I do? Do I have a big problem? It makes me suspicious especially since Madge died :-(
