Carinotetraodon travancoricus (Carinotetraodon travancoricus) – a small freshwater fish from the puffer family.

Occurrence

He lives in the state of Kerala in southwestern India on the Malabar Coast.

Characteristics and disposition

Dwarf spikers are cute fish with a playful disposition and unusual swimming style. They are only 2.5 cm long. Coloration of yellow-gold with dark spots.

Gender of young fish is difficult to distinguish. Adult males have distinct, dark lines under the abdomen and a pattern that begins just beyond the eye line. Adult females are often rounder than males. Puffers can grow in size (up to 2-3 times). Usually, when in danger, they fill their belly with water or air and thus try to discourage the predator from attacking.

One of the few fish that close and blink their eyes.

Nutrition and feeding

Like most puffers, they feed on crustaceans, live and frozen food. They are reluctant to eat dry foods . Snails should be regularly included in the diet – on their shells, the fish sharpen (grind) their teeth, which are constantly growing.

Aquarium

The fish can be kept in groups or individually.

Approximately 12 liters of space is recommended for one puffin. They feel best in a densely planted aquarium with numerous hiding places, nooks and crannies made of roots or stones. This arrangement will reduce the frequency of meetings and reduce aggression between individuals, as well as provide a diverse area for these curious fish to study. The light should be scattered with floating plants. Fish in such conditions are more active and bolder.

In nature, they inhabit stagnant waters, therefore too strong a current is not recommended. Puffers are very sensitive to poorer water quality, therefore frequent changes are required. They are not suitable for a social aquarium, tend to nibble the fins of other, free-swimming or veiled fish. With faster, more active fish, they will lose the competition for food. However, they can be eaten by fish much larger than themselves.

Quite good company will be small catfish, for example the estuary otos . Breeders keep dwarf spikelets also with shrimps (but with varying results).

Breeding

Successfully bred in aquariums. During spawning, males fight for females and often pay for it with their lives. Breeders suggest breeding in pairs or harems where there are two females per male.

A greater number of females reduces the risk of a single female being tormented by male courtship. Fish can also be bred in large groups. The spawning tank for a pair does not have to be large – 20-30 liters will be just right. You can use a small sponge filter or change small amounts of water frequently. We put large portions of small-leaved plants into the aquarium.

Fish especially prefer mosses such as Java Moss, Willow Moss. We increase the water temperature to approx. 27-28 ° C. Before the planned spawning, the fish are plentifully fed with live or frozen food, especially snails. Males ready for spawning appear slimmer and take on more intense colors.

The male chases the females vigorously, often nibbling and pinching if he is not interested. The chase usually ends in a thicket of low vegetation and the act of laying and fertilizing the eggs occurs. The eggs are tiny, transparent and therefore difficult to see (1mm). The female usually lays 10 grains or less. It is best to transfer the roe with a pipette to a separate container.

White-milky, moldy eggs should be discarded. Hatching takes place after about 5 days. After the next 2-3 days, the young begin their activity in searching for food. First, we give micro foods until they are large enough to take artemia. Due to cannibalism, it is not advisable to keep fry of different ages together.
