The L29 Galaxias Pleco! Getting around 10 inches this Pleco mainly feeds on Prawns and Snails, occasionally learning to eat off-the-shelf foods. When building an aquascape with this pleco in it keep in mind they prefer bogwood and darker rocks for them to blend into. Some tank mates for these fish include Larger Tetras, Peaceful Cichlids, and schooling fish. A minimum of 50 gallons is required for this fish but as always the bigger the better, especially with tank mates.
