The Red-Tail Red Eye Dwarf Puffer is a rare, fully freshwater species that maintains a small size and can be kept in groups in a large enough aquarium!
The Red-Tail Red Eye Dwarf Puffer (Carinotetraodon irrubesco) is a rare species that is native to Indonesia. It sometimes lives in loose groups and grows to an adult size of less than 2 inches (5 cm). Like many pufferfish species, it is very active and has plenty of personality. It is relatively aggressive, but is still compatible with many other aquarium fish species.
One major key to successfully keeping the Red-Tail Red Eye Dwarf Puffer in a community setting is ample space and décor. Males of this species are particularly territorial and will often claim and defend an area, so more plants, rocks, and driftwood will help to break lines of sight and create more distinct spaces. Like all puffers, this is a relatively slow-moving fish and will not be able to regularly keep up with faster-moving tetras, rasboras, barbs, danios, and rainbowfish. It will relentlessly attack the fins of slow-moving, long-finned fish, so fish such as bettas are not good tankmates.
Dry foods are often ignored by the Red-Tail Red Eye Dwarf Puffer, although sometimes groups of this fish will learn about new food sources by watching one another try them out. In our experience, it is not a good idea to rely on dry foods as a staple for this fish. It will, however, eat frozen bloodworms and other meaty frozen foods. Its wild diet mostly consists of crustaceans and snails, so it should not be kept with dwarf shrimp or other ornamental invertebrates. On a positive note, it will happily clear any aquarium of any small snails, including the “nuisance” bladder snails that inhabit most planted tanks. Like most pufferfish species, its beak needs worn down through regular feeding of invertebrates whose shells are still intact.
