yes, most (if not all)pleco's are nocturnal.
they will come out with light but you will see them more if you have moon lights.
yes quarantine for a month.that way you know if the fish are free of bacterial infections and parasites..I go one step more and treat all new fish for parasites. a habit I learned from an importer. most parasite meds are not all that harsh and the fish usually have few issues if any with the meds.
I bump the temp up to 86+ too.. bare bottom tank and keep it clean.
ich won't survive these higher temps. nor will most other parasites. ever wonder why the body will make your temp go up when your sick?
and don't add anymore fish till your tank is stable
