I try and keep my plecos segregated a bit, however its a little bit more because I dont want my SA cichlids to get too much meat.
My main tank has a Rhino, Clown and L095, they get a good mix of cichlid pellets and kelp wafers. Rhinos are basically garbage disposals. Not much is known about L095 diet that I can find, but their teeth suggest they are opportunistic eaters like the rhino.
Another tank has a hi-fin L200 which are known to eat a lot of veggies. That tank gets normal cichlid pellets as a staple, but I supplement a lot of veggies and kelp wafers.
I have another SA cichild tank with a large L330, L191 and a small L027c. The L330 will actively eat the cichild pellets as soon as they hit the tank, but I try to let the cichlids get the majority of them as I dont want him to get bloated since they tend toward veggies and wood. I supplement heavily with veggies and kelp wafers.
My last tank has(with plecos) is my meaty tank. It has 2 Angel fish and an oligosarcus robustus. The robustus is a piscavore, but will readily eat cichild pellets so I feed the tank a staple of cichild pellets, but for this tank I supplement with carivore wafers, kelp wafers, chopped shrimp, and fish fillets, as well as some fresh veggies. It houses a Heterodon(vampire), L201, L114, 2- L264 sultans, an L091, as well as a random rubbernose. The rubbernose doesnt seem to eat any of the meat that I have observed and has maintained proper weight/form.
