Dirty Tank

January 19th, 2006, 09:39 AM
I have a 30 gallon tank, I have an algee eating fish that's making such a mess of my tank. I don't know the name of the fish, but he's long, grey and he sucks himself to the walls of the tank. I don't have any algee in my tank, so I feed him tablets that's recommended by the petstore. Every two minutes, he's going to the bathroom. The tank is always dirty becaue of him. Does anyone have any idea what I should do?

I did research, this is the name of the fish Suckermouth catfish. I also included a picture

Suckerfish, plecos and the like are lazy, dirty fish. But that's just my opinion. You may need to clean the tank more often, I try to do it once a week. 25-30% is usually enough, gravel vac as much of it up as you can. People with planted tanks and high-light and CO2 often change 50% of the tanks water on a weekly basis.
You can also feed less, give half a wafer as opposed to the whole thing. He'll hunt down microscopic algae if he's hungry, he'll also clean up left-overs from the other fish if he's not getting the free meal as often.
If you want to try other algae destroyers that make less mess there's the wonderful and always busy oto catfish, they like to be in schools and they really earn their keep. They make smaller green poops that disappear into the gravel nicely. Small cory cats like the pandas and hasbrous are also great scavengers, and they don't make as much mess.
Hope any of this helps!

Your fish is a Common Pleco.
The first reason it is messing up your tank is because
a common pleco is wayyyyy too big for a 30g tank.
Do you know that this fish will grow to be about 2 feet long?
Yes, 2 feet, 24 inches! Maybe even bigger.This fish
actually needs a tank 75g-125g to live happily in.
All they do is eat and poop.
I have 2 suggestions for you:
1) Sell the fish back to the pet store and buy a smaller, much more
suitable algae eater such as Bristlenose Pleco, Rubbernose Pleco,
Otto Catfish, or a snail.
2) Start doing deep gravel vaccuum 35% water changes every 5-7 days.
This fish will literally be causing the ammonia levels in your tank
to shoot through the roof, making the tank hazardous to all other
tank occupants.
