one of my mates has one, and he never sees it. bit gutted as it cost him a lot of money. hes looking to rehome it simply for that reason, but isnt willing to give it away due to its value.
I have read that they won't tollerate any other bottom dwellers, and i am thinking of selling this one if it shows aggression as i would like to move my L001 across to the new tank along with a few BN's and maybe some other catfish.
my friend has a lot of bottom dwellers, including other syno's, plecs and hopolo's. as i said though, he never sees it, so has no idea of its temperament. however, there are no signs on other fish fighting.
