I have a school of discus, tetras, and panda corys' (or what is now left of it)
I originally had 14 neon tetras and 5 panda corys' but when I woke up today there were only 5 tetras and 1 panda cory.
Could it be that my bristlenose pleco is carnivorous?! I also notice that he hasn't been doing his job lately.
There are areas of algae where he doesnt touch and he tends to sit behind the filter pipes.
What should I do? Sell him? And if I do what would be a nice substitute?
 
Never had my bristlenose attack any cory or even kill another fish.. unless you watched it, I would guess its something else

Check water params and check to see if there is any dead fish in filter, tubes, or intake. Its also possible that some of the fish couldve died and then become a meal

Personally i dont think the BN picked off all those fish. I think it was what i said in my earlier post or some disease or problems with water params. But i saw you asked about what you could use to replace him to help with the algae. Me i would put in live plants. Discus tanks, especially large ones with other schools of fish can be stunnin as planted tankes as long as they are upkeeped corectly. The plants will use alot of the nutrients the algae needs to grow, so less algae

I doubt it is the pleco. Especially not if you are talking about 9 tetras and 4 cories. I wouldn't have room in its gut to do that overnight. The discus could be responsible for the tetras, but the cories are unlikely victims of anyone unless they died of water parameters or disease and someone else ate them.

Discus are notorious neon tetra eaters. They are cichlids, after all. Occasionally you'll find discus who won't touch them but for the most part they will hunt neons and other small shoaling fish. A lot of people choose to keep cardinals instead because they grow larger and tolerate the warmer discus temperatures better. They could still eat cardinals if they wanted to, though.

I doubt they touched your cories unless the cories were extremely small. Check really well that they're not stuck in/under something or hiding.
 
I had a bn pleco that stopped doing its job. But he wasn't feeding on fish, he found blood worms an easier meal than algae. On the other hand, my discus killed about 5 blue rams. I checked parameters, everything was normal.
 
I had Discus and Angel fishes killing off my smaller fishes too. Really doubt it is the job of the BN. The BN is probably feeding on the remains of the dead tetra....
