ammonia spiked at 0.1 today because y-day i fed them a LOT
temp 27C (83f) (coming down after a ich treat)
theyr colour started degrading about 2 weeks ago.
nope none of the other fish are stressing them, they actually pretty much play with the zebras, and moly's
they are also the only ones losing color, the red platys are incandescent red, the black molys and white molys are perfectly elegant in colors AND ways of acting (swiming feeding) the neon tetrat are bright as brand new, zebras .... well not much of a color except the stripes, and the corys are pinky as always
so all in all ... only my guppy lost color, they are active as always, but no longer reproducing nor having bright colors as before
so i guessed it was all about the food
