I dont feel like pleco's or any algae eating fish are nessisary with proper maintance.. sorry had to say it..
I havnt had GBR's or any Ram's.. columbians are cool.. and my local pet store has some golden ones that look better then the pictures Ive seen of the GBR's..
If you have seen the golden ram's in your area.. I vote those..
columbians would be my second choice (since they are not quite as delicate as GBR's)
and if your water is pretty good out of the tap (very little if any N and PO4
) then GBR's
