Well here's the story. I had a 10 gallon tank that was starting to get algae problems. So when we bought a few Tetras to round out the tank, I also bought a Pleco. (Yeah, yell at me later for putting a fish that grows to such a size in such a small tank). Either way, he did an awesome job of cleaning, but after he cleaned it out (and we started feeding him algae pellets), he started becoming pretty anti-social, just crawling under a decoration.

Well I came into a 20H tank right about the time I was moving to a new apartment. So we had the luxury of setting up the new tank ahead of time, moving a few fish over to get it cycled, and bringing the rest over later (We had about a month and a half overlap between the two leases).

Either way, about a week or so ago, I've noticed some brown algae growing on some of the silk plants in the back. Now I've been feeding algae pellets to my Pleco (who's taken to sitting inside one of the decorations again). But he not cleaning the plants. I figure it may be because they're a bit close to the bubble curtain, so I let it slide. but now the algae is growing elsewhere, and he still isn't touching it. Oddly enough, he's trying to clean the sides of the tank, but the algae is starting to show up in the gravel, and on the top of a cave thing (which, oddly enough, we bought for the Pleco, but has been taken over by the Danios. :) ).

So has the close quarters of the tanks just stressed my pleco beyond the brinks of sanity and hunger? It's starting to creep onto the carbon filters of the undergravel filter, and I'm afraid that if it gets in there, it won't get out.

Thanks in advance.

First, if you cut down on how often the lights in your tank are on you should start seeing less algae. If not, is your tank near a window?

Next, try not feeding your pleco any algae wafers for about 5 days to see if that spurs him to clean the algae. Then be sure to feed him regularly again (this shouldn't be a constant thing).

Finally, if you have a common pleco (that gets to about 18" or more) you may want to trade him in to your LFS for 3 otocinclus catfish (they school) or a smaller species of pleco like a bristlenose. These would do the same job of cleaning your algae without getting to an unmanageable size (though the bristlenose will still be a little bit large for the 20H if it is heavily stocked).

Why didn't I think of this? That's 6th grade science, there. Heh.

That's probably what I'll end up doing. My nephew won't like it (he just loves Big Pappa), but it'll be better for both of us in the long run.
