Temp should be around 78-82 F For ph mine is doing fine at around 6.8 for tank mates mine is very aggressive and curently it won't accept any tank mates i'm hopeing that when i get it in a bigger tank it will let some tank mates survive i've heard others aren't very aggressive
For minnimum tank size they will get around 8'' some are kinda of lazy mine is very active so i would recomend a 40 gallon breed as a minnimum tank size
gets to 10 inches max.
usually only 8 inches.
usually not aggressive to anything that doesnt look like another wolf.
fine with tankmates that arent too aggressive and arent too small to eat.
45g tank should be fine.
40g breeder minimum.
eats just about anything.
not too picky about water paremeters.
but arent as hardy as malabaricus.
