ok, even small plecos such as bristle nose plecos are a HUGE bioload...I had a 2" one in my community tank...in one week i went from no measurable nitrates to 10ppm!!! they poop alot, they eat a ton,and they are some of the messiest fish in the hobby...dont belive me? look it up.
they also are a fair algae eater at best. dont expect them to eat algae off of plants...my BN only went for the soft algae on driftwood and and soft algae on the sides of the tank.
get yourself some snails or a school of ottos...much better algae eaters and not a bioload on the tank...
in my ten gallon i actually keep junk snails...the ones detrimental to plants, but I only keep a couple floating plants and some java moss in the tank. those little buggers multiply like mad and keep the tank spotless. sometimes in the middle of the night i will go and scrape baby snails off the side of my glass to keep the population under control...other than that I let them do their thing.
but yeah, it says you have a pleco in a 30 gallon...bad idea...even a dwarf is too much for your current amount of fish in a 30g...
