tips with L048, L114 and L24
 

need tips on L048, l114 and l024. I currently have a 3 inch L048, 2 inch L114 and 4 inch l24 in a 75 gallon tank.
This tank is exposed to sunlight and gets warm during summer.
about 30+ Deg celcius. will my plecos be able to tolerate that temperature?
also can they do well together? currently still lots of space in my 75 gal. but worried with size difference and maybe aggression?

how often do i have to feed them and how much?
i dont see them at all hehe :)
