Red tail Lasiancistrus L178 very very rare pleco plec I have a group of Red tail lasiancistrus L178 for sale, dont want to sell these but mooving house and have no room for the fish tanks so unfortunatly these have to go. These fish are very very rare to get hold of and was told only 6 people have them in uk, if have a look on google they is hardly no information about these at all no reported breedings of these at all. They are a very peacefull fish, i bought a group of 7 of these to have a good chance of getting male and female as lack of information on how to sex these have noticed 2/3 of them have slightly different shape heads which could me male female either way not sure. Really dont want to sell any of these but mooving to smaller house so tanks have to go (iv tried persuading the other half to move to a bigger house but she wount have any of it, was told its me or the fish so they have to go which may well be the wrong decision lol . will be collection only from swinton south yorkshire I WILL NOT POST! please call or text on 07557055325 dont use contact option below as i cant acces that email no more. open to reasonable offers £150+ for the group of 7.

Please note the fish was just put in this small tank so could get some close up photos they would need a large tank.
