Freshwater Fish

Three Beacon Pleco.

A small, attractively marked pleco picked from our tanks — a peaceful, nocturnal algae grazer that earns its keep on glass and driftwood. Give it caves and clean water; ask us about the specific type currently in stock.

Live animals are sold in store only — we do not ship fish, coral, or invertebrates. Every animal is acclimated and health-checked in-house before it reaches the sales floor. This is a species we carry — it's most likely in the tanks around delivery days, but live stock changes daily. Please call (814) 456-9445 to confirm availability before you drive in.

Good tank mates

This is a store pick and the specific type and temperament aren't recorded, so compatibility depends on the individual fish. Plecos generally keep to themselves but can be territorial over driftwood and caves, so give each one its own spot. Call us about the type currently in stock and the right tankmates for your setup.

Good to know

Plecos are South American suckermouth catfish in the family Loricariidae, armored with bony plates instead of scales.

S
Striped Headstander
South American mid-water characin explicitly named on the Seriously Fish L. triactis profile. Although Anostomus is known to nip the fins of soft-finned fish, L. triactis is a loricariid with bony, spined fin rays and full body armor — the nipping risk does not apply. Occupies the upper-to-mid water column away from the pleco's cave territory, and shares the same requirement for fast-flowing, well-oxygenated, soft-acidic water.
S
Slender Hemiodus
Peaceful, fast-moving South American schooling characin explicitly named on the Seriously Fish L. triactis profile. Occupies mid-water and does not compete for the pleco's cave territories. Temperature overlap (25–26°C) is real, and both species require soft, slightly acidic water with strong flow. Best kept in groups of 10+ to maintain natural schooling behavior.
S
Sterba's Corydoras
Warm-water-tolerant corydoras explicitly named (genus level) on the Seriously Fish L. triactis profile. Corydoras sterbai tolerates temperatures up to 30°C (86°F), making it the one Corydoras species whose full thermal range covers the pleco's preferred 25–30°C. Occupies sandy open substrate rather than the rocky cave territories the pleco defends, minimizing competition. Peaceful and robust.
