some months ago i picked up 3 L204's from my local fish store at approx 2" size.. and put them in my planted 20h to grow out abit. Well now I have 1... and he is pretty evil. anyother pleco species i've tried putting in there. includeing a whiptail,and a clown pleco. have been quickly singled out from the tetras and platy and attacked. After loseing the other 2 L204's "mysteriousely" the aggression towards the other plecos i try to put in there mkaes me pretty sure he's just one mean bugger. any one else have experiances with this? I plan on trying to introduce a few more with this guy into a 40 breeder in the next few monthes when the current fish in that tank get moved into a larger tank. any suggestions for hopefully succesfully keeping a colony or pair ? If he wasn't so pretty and always out and about and active I'de take him back. evil fish.. lol.. and I say He because the head shape looks very male though I haven't seen the bristles on the tail region. I'm guessing he's still a teenager? or very young adult at his size now about 3"?
