Size / Weight / سن
بلوغ: Lm ? range ? - ? cm
Max length : 6.4 cm SL جنس نر / بدون خواص جنسي; (Ref. 12251)
خارهاي باله پشتي (کل) : 14 - 16; شعاع نرم باله پشتي (کل) : 10 - 11; خارهاي باله مخرجي: 3; شعاع نرم باله مخرجي: 7 - 8. Diagnosis: lower pharyngeal jaw robust and massive, with a large, heart-shaped dentigerous plate, covered with numerous fine, regularly arrayed teeth; mouth not squared or obtuse; ventral margin of lower lip smooth; ratio of lower jaw length to lower jaw width > 1; oral jaw teeth fixed with non-spatulate crowns (Ref. 26738, 81260). 13-16 gill rakers on first arch (Ref. 26738).
Prefers sponges, but small amounts of diatoms, plants (mostly algae) and detritus have also been found in their stomachs (Ref. 52307). Pair-bonding, open (Ref. 52307) substrate brooder/spawner (Ref. 52307, 81260) with both parents guarding the brood (Ref. 52307). Usually spawns in shallow waters, building colonies of up to 6 pairs separated by about 30 cm; eggs are hidden between leaves and pieces of wood (Ref. 52307).
