Description: Males have a greyish colored, faintly mottled body, while their belly and underside of the head are white. There is a broad, pale stripe on their flanks that extending from the eye to the base of the tail, and a similar wedge-shaped bar on the back of the fish. All males have a broad, red mid-ventral stripe, and sometimes the dorsal area is also red. The tail and the dorsal fin are red, while the rest of the fins are mostly colorless. Females also possess the faint broad stripe on their flanks, but this is often interrupted, and they also have another two or three undulating pale stripes on the body that form an irregular reticulated pattern. They also have white bellies, but there are a number of brownish stripes on it, and a darker blotch at the anal fin area. The fins are mostly colorless, except the dorsal fin that has light sptripes, and the tail which is yellowish with several darker bars. Both fish have red eyes.

Puffers can inflate their stomachs with water or air, and become 2 or 3 times their normal size so can easily scare away many potential predators. Like most puffers the Red-tailed Redeye Puffer is very sensitive to bad water conditions like nitrates and ammonia, so regular partial water changes, and an overfiltered aquarium are essential. Their teeth grow continuously and may become a problem, so hard shelled foods such as shellfish and snail diet can help to grind their teeth down.

There are only a few information available about their aquarium breeding. During courtship the male display to the female by darkening its colours. After a couple of hours the female deposits a few hundred eggs among the fine-leaved plants or on the decoration, and the male fertilizes them. The first eggs hatch in 65 hours and the larvae become free swimming after another 3 days.
