So, I have a large semi-aggressive tank, but I wasn't sure if denison barbs were okay for semi-aggressive? Another question is if my rainbow shark would see them as a threat or not?

I have a peaceful community tank but it doesn't have a current, nor do I think it's big enough (just a 20 gallon tank).

p.s. - sorry for all the posts lol, i think im killing you guys on the inside

I got a group of four two years ago in May. They started in a 4 foot tank with a baby Oscar. That lasted until she was big enough to eat one of them. The remaining three were moved to a four foot community tank. I moved them to a 6ft tank a few months back due to thier size. At four inches long now they can cover the four foot tank with a single flick of thier tail.
They get along with anything really that I had them with. Thing is they are very torpedo shapped, so any cichlids will have to be on the smaller side, cause we all know if it fits, a fish will try and eat it.

All was fine for about 8 months....

Till one day she had enough and ate one.....
So I suggest what ever you house with them be a smaller size so they can't eat them.
My Roseline sharks are voracious fry eaters as well, so if planning a breeding tank I would skip them.
They do make for great tank cleaners tho, always eating everything from algea, to fresh poop right from the cichlids butt.

How big is the large tank and what else do you have in it? I think they'd be ok with rainbow sharks as long as they have adequate numbers and decent size.

The 'big' fish in my tank are an angelfish, an electric blue acara cichlid, and the rainbow shark, none of which i think could eat a roseline.... maybe. My rainbow shark is fairly young, so he's not too big right now.
I have 5 tiger barbs, a king betta, an albino bristlenose, and a pictus catfish as well.

The tank is 100 gal. Would I be overstocking if I got a few roseline?

Hah! I don't have any fish that get big enough to eat roseline sharks, but it's good to know. I have definitely thought about housing oscars. They're beautiful/intelligent fish.

Technically you could add a group of 6-8 if you keep up on parameters. I am concerned because you are mixing fish of different temperament and requirements and thus potential issues may arise. The betta may be nipped by the rainbow shark and the barbs. The betta likes fairly slow water, dim lighting etc. The denison barbs do best at 73-77F with clear, fast flowing water, etc. Instead of adding more fish, how about getting 5 more tiger barbs (presuming they don't nip at the angel or betta) and 3-4 more pictus cats?

The betta doesn't have long, dragging fins that tire him out- he's more akin to a 'wild' betta with short, spotted fins (he's also bigger). He's very active, and none of the other fish have picked on him. The shark, despite his size, is actually cautious of the betta and will avoid him. I may move him to another tank in the near future.... I looked over just now and he is currently threatening the cichlid, haha.

The barbs haven't bothered the angelfish, and I only got 5 of them to make sure nothing in the tank would get pestered by them, since I know they get overly confident if there is enough of them.

I think getting more pictus might be the best way to go, then. I don't want to make a giant mistake and hurt fish in the process. If I ever get roseline sharks I suppose it'll have to be when my fish have passed on. That'll be awhile lol.
