But yours seems to stay light due to the sand imo. And that pic of the black was from maybe a month back maybe 2, now he's a brute and looks to be 10 inches now. Growth is steady once they gain weight, mine took two months gaining weight and then started growing altogether. Sorry for the cloudy water, idk why it got like that the last few days, I did amy weekly water change yesterday and it's still cloudy. I was thinking of doing just wolves and bichirs. My wolves play well together so far.
