This small goby is a free swimming species, in contrast to most of the other gobies. Maximum length is about 4-5 cm. Territorial males become bright yellow and also develope larger fins with dark bands. Females are much paler in coloration and have translucent fins.
The species is restrictet to Sulawesi and even on that island it occurs only in two lakes, namely Towuti and Mahalona. The water in these lakes is very warm (29°C and more), very clean, slightly alcalic (pH 7.5) and the conductivity is about 225 µS/cm.
The charming fish already spawned in aquaria. The eggs are laid open, attached on vertical structures in a circle-round batch. However, to the best of our knowledge there was no complete successful breeding so far.
For our customers: the fish has code 436812 on our stocklist. Please note that we exclusively supply the wholesale trade.
Lexicon: Mugilogobius: latin, means “mullet-goby”. rexi: dedication name.
