Should I be concerned about this dark spot that has popped up last month or so on my bristle nose pleco?
It seems to have gotten a little bigger. She seems fine just looks strange.
she’s in the tank with her mate and 8 black neons and a few snails.
water temp is at 79
0 nitrite
0 ammonia
little to no nitrate planted 75 gallon.
weekly water changes.
Ph is at about 8 I live in Texas and hard water is it here.
Any advice is welcome
thanks
