Reef2Reef is primarily a saltwater forum but some of us also keep freshwater tanks. A 100 liter tank is equivalent to 26 gallons. IMO this is too small to keep even juveniles and much too small to house a full size adult red belly piranha. This is a fish that can reasonably grow to 8" in an aquarium unless it is stunted with poor care.
