Unable to edit previous post sorry for double posting. Anways can someone else tell me what could this be...
Red Belly Piranha dark lower jaw
- Thread starter TheQuarterMile
- Start date
These injuries may be territorial but regardless poor water quality can rile these P's up as well as high temps (80°+)
Try lowering temps to 74-76° and cut the light duration or intensity by removing a bulb or re positioning it higher or using black water extract.
And those "burn marks" look to me like the fish was cornered for awhile rubbing against dw, rock or piece of decor thus removing scales and inflicting a wound. My shoal has done this once before and it looked very similar.
Lower temps, don't over fed, keep up on wc, test water daily and lower light intensity and light duration. You could even throw in some guppies as dither fish to put more attention on them instead of the prized piranhas!
Either way you have plenty of solutions and imo lowering temps and less light has helped loads. Also stronger currents can break up aggression too, a korillia circulator may do the trick too: http://www.petmountain.com/show_product/11442-522698

And that wound was either when you feed them and they went for the same piece and one got chomped accidentally, or they faced off and one got bit. Its no disease or anything , simply got its lower lip bit off. Remember these fish literally have RAZOR SHARP teeth!

Thanks for the info.. That lower jaw seems to have healed. It was a bite mark and now the shoal seems to be fine. All have picked their spot in the tank. I change almost 40% water every 7-10days. Also vary their feeding habit and time. Regarding temperature, I have switched off the heater since the room temperature is around 75-77°F so not worried about burn marks. But recently one piranha had got this dark spot on the top. Not sure what it is. Is it something to worry about?
Can anyone tell me what that is? Still hasn't gone!
