I bought him / her in November last year, and he / she was about 4 maybe 5 cm long. I don't even know what pleco it is, but it's growing very nicely, measured last night, it's 9 cm long already. First started out in my 150 liter tank, with gold fish, then goldfish went to the pond, then came the guppies, and i wanted convicts, so he shared a tank with them, but they started abusing him... So i removed and moved him to my 40 liter tank in the room, but he wasn't happy at all... So now, he came to his final home, in my 5 ft tank... He loves staying in the ship, and waits for his two pallets morning and night time... Got this pic of him just after he ate last night.
