I don't think it's only the BN pleco that's causing the ammonia - it's the combo of the waste of ALL the fish in there - we also don't know how long your tank has been running - ammonia usually signals an uncycled tank, too small of a tank and not enough large water changes.
Do you own a test kit? Plecos don't belong in small tanks like that no matter how small they start off (all fish start small - that's how pet stores are able to house so many of them in their tiny tanks until they are sold).
