Do you have a 100+ gallon freshwater predator tank and an interest in one of the best known fish of the Amazon River Basin?
We are trying to find a home for a fully grown, 9 inch, Red-Bellied Piranha!
He's getting a bit too big for his current 90 gallon aquarium, and his owners would love to see him thrive in a larger system!
Please reach out to us through messenger if you are interested, or know of someone who might be able to give this sharp-toothed fish a good home!

Adding live phytoplankton to a tank helps clean the water by removing nitrates and phosphates, feeds copepod populations for detritus cleanup, and helps directly feed corals, resulting in extended polyps and a pristine look across all surfaces!
