My pleco is too large for the place he used to hide in, now I'm stuck with what to give him to hide in/behind. He's about 8 inches long. I put in a thick glass long vase today, and half buried it. Then I put driftwood on top of it. The fish love it, he hasn't tried it yet. I can't think of anything else. I'd love a cave he could swim through or because my tank is 24" deep, maybe something that goes from top to bottom that he can hang on too behind it. Or any suggestions would be great!
