The egg-carrying buntingi is known to be found in a freshwater environment within a pelagic depth range.

The maximum recorded length of the egg-carrying buntingi as an unsexed male is about 8.5 centimeters or about 3.34 inches.

The egg-carrying buntingi can be specifically found in the Lake Poso in central Sulawesi.

[6] Male and female egg-carrying buntingi can be distinguished by the size of their pelvic fins.

Recent studies have shown that egg-carrying buntingi tend to reproduce during rainy seasons because it causes the lake level to rise.
