Thanks, that’s very helpful! I’ll need at least a 2 inch diameter tube by that measure.

Any guidance on length?

We have 1 male and 2 female Ancistrus cf cirrhosis, the largest 2 are about 5 inches long. I got a ceramic pleco tube with a 1.5 inch diameter opening that’s about 6 inches long that was reviewed as being good for breeding bristlenoses. When I put it in the tank, I realized it may be too small: the ...

Well as long as we didn’t wind up with anything that will get huge and eat all the plants, we’ll be happy. Here’s a dorsal shot of the striped pleco. Based on proportions I didn’t really consider options outside of Panaqolus.

Probably not much of an improvement but I cropped these a bit.

Thanks! I was wondering about the larger one being L448 and the stripier guy being P. maccus.

We recently added two “clown” plecos to our tank. They look to be two different species. The one with the more patterned snout is ~50mm total length while the more cleanly striped one is about ~40mm total length. Are either of these actually Panaqolus maccus?
