Injured/sick Ruby Shark? Pic Attached

[James_Wayland]

Hi everyone, my first post and straight into a disaster!! possibly, had this ruby shark, a male, for around 5 months, and he seems in perfect health, apart from the gaping hole thats appeared in his side!!! eating well and behaviour seems normal, and the only possible aggressor is a pleco, only 4 inches, or an apple snail!!! but cant find anything to suggest a disease it might be?? watter parameters are absolutely fine, 0, 0, trace, so any ideas would be of great assistance!!!

Thanks, James

I have no clue what it could be...

I've heard of this in goldfish/pond fish,i think its a bacterial infection,maybe caused by poor water conditions.

I see you only do a 20% change every 3-4 weeks...

If not treated it may affect the whole tank.

I may be wrong,so best wait for someone more knowledgeable to come along...

Looks like an ulcer to me, treat with a Bactericide such as Waterlife MYXAZIN.

thanks very much for the replies guys, will run out to grab some of that tomorrow, dont suppose you know if this is safe with invertibrates? I will of course check the bottle first, just after a heads up?
Thanks, James
