hey, i have a 20 gallen guppy tank, 8 guppys, my common pleco died, i need to peplace him as tank is getting dirty, will this pleco be ok with my guppy?
Your best bet would be to get a group of Ottos as they are more efficient when it comes to cleaning algae. A group of 5-6 would be fine in that size tank. A Bristlenose would be ok but some of them can be quite lazy and won't necessarily eat all the algae.
