In a 75-gallon tank, plan on about 1–2 Bristlenose Pleco, leaving room for tankmates and filtration headroom.
Why
Stocking is driven by adult size and waste output, not just fish count. Bristlenose Pleco reaches about 5" with a heavy bioload, and needs 73–81°F water at pH 6–7.8. Always cycle the tank and test water before adding livestock.
