I actually don't think Texas has that many species of Suckers.

There are the three species of Buffalo: Smallmouth Buffalo, Black Buffalo, and Bigmouth Buffalo. ( Yes, "Big" mouth. )

They are all in the sucker family.

As far as true suckers like the one posted above, I think we only have a handful of species. None of them are listed at TPWD if that gives you an idea of how common they are.

I believe we have a few species of Redhorse Sucker, Golden Redhorse and Grey Redhorse, but I may be mistaken. I believe we have Blue Suckers, and a few other species as well, possibly White Suckers and Grey suckers.

I think in Texas they are mostly confined to a few rivers and creeks. The one I caught was in a small, spring fed branch of the Concho River in West Texas. It's the only place I've seen suckers in the state.

But I think there are some in various places on the Trinity, The Guadalupe, possibly the Rio Grande, and some other smaller creeks and rivers. Especially those that are spring fed, like the one in question here.

Suckers generally prefer cooler water, which is why they don't do well in most Texas lakes and rivers.

I've caught many, many different Suckers myself, most of which were in the Redhorse family. But all the Suckers I've ever caught, save the one from the Concho, were up north in states like MN, WS, MI, and so on. I imagine most Texas anglers have never even heard of them, because they're not caught or seen often.

Rivers will also sometimes hold really big fish.

I just found out recently that someone shot ( Bow-fishing ) a 31lb plus common out of the Concho! That's right by where I used to live, and I never even realized it had fish anywhere near that big in it. Don't know why, oh well...Maybe we'll need to take a trip out there and do some serious carping. If there's 30+ commons, I bet there's 40's...

I have caught several quillback's in texas

Yep, River Carp Suckers too.

Those are both rare species. Are they considered part of the sucker family? Both cool fish too.

Also, where did you catch Quillback and River Carpsuckers in Texas?
