These pleco's are awesome. Mine seems to be very nocturnal, but he will come out during the day. After I feed the fish bloodworms or during quiet times of the day we can find him along the glass or sifting in the gravel. But, even then if there is any movement in the room he quickly returns to the closest cave. I have a slate cave on each end of my tank and a large piece of driftwood to separate them. My Adonis is in a 280 liter tank with a variety of cichlids. The cichlids don't really go around him, but when they do they almost get a tail to the face. He protects the place he is in. My Adonis is about 16-17 cm and I've had him for a few months. They are a great addition to any large tank, and I would highly recommend this pleco to anyone.

This is a beautiful fish when small. Once they get larger than about 20 cm they lose coloration. They are active for a Loricariidae, and you must have a tank in excess of 1000 L to keep this fish for its whole life as they grow to 90 cm.

I got this Pleco when he was about 6 cm, and he disappeared away into the 340 liter planted tank. You would only see him the odd time. After he was there for about a year he had probably doubled in size, with the filaments on his tail becoming very long. You would also see him more during the day as he got bigger, but he would always be close to the bog oak. When I was moving my tank, I fished him out and stuck him in a smaller tank which I left in beside my computer in the office. This was just a holding tank, with a load of plants and no filter. I dropped in a couple of bits of wood since that was where he liked to be in the big tank. Then, at night I heard this weird noise. We were in a new house, so I assumed it was a machine somewhere making it, but after a bit I realized that the Adonis pleco was making the noise, I could catch him at it. He was sitting on the wood, grinding it with his mouth. They seem to eat wood! You know where he has been, because there is a pile of ground up wood crumbs near him. Anyway, he is back in the main tank now, and is spending half his life herding clown loaches off his wood. He is a cool fish. Other than the massive size they grow, I can't see any problems with him.

I bought my Acanthicus adonis Loricariid over two years ago. He was just over 5 cm. His large yellow spots were what lured me to him, but he reeled me in with his antics. I was not swayed by information about his adult size and disappearing spots, and have always kept up with his growth. Even slight thuds will send him hiding, but he is otherwise boisterous and a very comical feeder. When chewing on a veggie, he will roll in the water carelessly/blissfully. Believe me, they DO get 100 cm long. I've been reading about them for the entirety of his presence in my tanks. Once they are about 15 cm long they grow slowly but steadily on a well-rounded diet of fresh and pelleted foods. Asparagus will cause growth spurts, so feed accordingly. Mine is now over 25 cm long and it's a real waste race in the 280 liter. Only an angelfish and a betta accompany him. Be prepared to house him virtually alone or with large fish. At full size, I assume he will need, at an absolute minimum, around 1500 liters to play in. By the way, watch out for the spikes near his gills. He can use them like landmines under a finger.
