My Pleco, "Grunge", is definitely my favorite all time fish. He has grown from 8 cm to 33 cm in just a year, and when he raises his dorsal fin I am in awe at such a mass of fish. He is very docile and gets along well with the other few fish in his tank. I love to watch him glide through the water in the same way an Eagle soars with the wind. And his algae-eating ballet gives me constant amusement. His favorite place used to be hanging upside down on a piece of driftwood. But he has since outgrown the wood and sleeps with his head tucked under it. When I feed he will come out immediately and suck on the shrimp pellets, sinking tablets, and algea wafers. He is also guilty of eating Angelfish eggs. Nothing seems to bother him, even my hand touching him as I move rocks and plants around the aquarium. The only bad thing about this fish is that he does poop a lot. The first night I had him I awoke the next morning to what looked like something kids had done on mischief night! Poop strung everywhere. But he is a grand fish with a very peaceful heart.
Often called a "worker catfish", it is very commonly available. Usually hiding during the daylight hours, it will venture out to the open tank during nightfall. It will take away all your regular green algae problems in a couple of days, so it must be fed with sinking vegetable disks often enough. Growing to a size of 60 cm or about 2 feet, this fish is definitely not for small tanks! Beware, as this fish gets older it becomes much more agressive. Some full grown plecos have been noted to stick themselves on the sides of large fish and eat the skin.
We were having a real problem with algae in our horse troughs so we went out and got a couple of Plecos. We put one in each trough. It has only been two days and we can already see the bottom of the tank where the larger one lives. The little Plecos have a lot more work to do, but we can see a significant difference. I love just watching the larger one cleaning away on the bottom of the trough. I love these little guys (?) or gals.
Plecos are pretty good fish, are gentle toward other fish, and don't get rid of too much algae but do the job. They can live in water of 23°C and poo a lot!
I recently bought a 15 cm pleco to clean the enormous amount of algae out of my 320 L Discus tank. I was shocked when the next morning every filament of algae had been consumed and redistributed around the tank through the rear of the fish. He (She?) gets on well with the juvenile Discus and only the dominant one gave the pleco any hassels, this thankfully only lasted 48 hours or so. A good community tank fish, interesting habits and great size potential make him my tanks star for some time to come.
I recently bought a fairly large Pleco to put in my aquarium. As I put the fish in the tank, I found the hard way it had spines on its fins. They seem to go well with the fish in the tank, which are 2 Oscars and 2 Mollies (donīt kow why the Oscars donīt bother about the Mollies.. but anyway), these fish are really good for the aquarium, as the Oscars are the messiest eaters I have ever seen, so the Pleco hoovers up the mess left by the Oscars.
