Wow! Thank you for such comprehensive feedback.
Your concerns are mostly the same as mine, for starters the whole tank doesn't get much meat.
I'm talking a block or two of bloodworms and some krill every two weeks or so, high quality pleco pellets every day or two and raw veggies once a week. In addition to that I feed my mid and top dwellers marine flake and new life spectrum pellets so they get whatever they miss from that too, so the diet is varied but not too high on meat. My worry is that my more timid fish aren't eating enough, but I can fix that if it becomes a problem.
As much as I love my royal, it is not a permanent resident of this tank. I bought it a few weeks ago because it was about to die and I knew I could help, he is now healthy and will be re-homed eventually.
The punctatus was an impulse buy that once I identified later I knew he wasn't going to stay with me too long either.
I have many friends here in town with big tanks so passing these guys on shouldn't be too hard.
As for the Triactis, nine and a half inches in a few years seems manageable to me and it's my favorite, so he stays.
I work at my LFS on Sundays so there will be bigger tanks eventually, I got this 75 for free!
As for hybridization, I did not know that was frowned upon until today.
I don't believe it will happen due to a lack of, and competition for caves. If they did manage to breed somehow all the fry would surely die.
I knew there was some risks in going for a varied loricariid community, but I have seen so many videos of them online and figured it would work itself out. I had two smaller freshwater tanks for a while and combined them into the larger one to save some space and stop complaints from my roomates, once i'm free of them more tanks will come into play.
My main concern has been with fighting, of which there has been very little. A good friend of mine (who has kept way more than myself over the years and frequents these and plecoplanet's forums) suggested that if I were to have all my plecs together to over crowd a bit to deter territorial behavior, if they can't establish set territory then they will just be on the defensive and keep to themselves. It seemed logical and over these last few weeks appears to be panning out,
but I am still worried about them.
As for Vegas, I have been extremely disappointed in the lack of cool wildlife in my area. I saw a gecko on my house once and that's been it.
