Just a few left of bristlenose plecos, about 1.25" big.
They are excellent algae eaters and can only get to a maximum size of up to 6" big (but usually 4-5").
They must be provided with some driftwood as part of their dietary requirements and a place to hide. They must also be fed with algae wafers, vege flakes and pellets, fresh or frozen veges such as zucchini, carrots, beans, lettuce, peas, etc.
I only have very few left so hurry before it's all gone.
