Flagtail if fish are large bristlenose pleco for smaller tanks and tank mates. Flagtails get very large 16 inches or so.
How's the bushy nose in terms if producing waste (pooping!) is it as much as the common pleco? If so , the. It's a no go! As for tank size , I have a 180 g but it's stocked already ... Wouldn't want to over stock.. But if I'm swapping a flag tail for a pleco maybe it'll be the same? (What type of flag tail? As there seems to be a couple dif ones) thx so much
16" would be a very old well taken care of specimen. I don't think I've ever come across one this big. Mine was maybe 12-14" and that was in a 750g. 12" is much more common in aquariums. Yellow tails are supposedly a little smaller.

Just put my order in at the LFS for a flag tail and traded in the pleco... Thanks for the advise! Hope this fish works out! May look into a bushy nose too...
He'd (FT) work out fine in my 180g correct ? (Seeing you had 1 in a 750g)
