Size 250mm or 9.8" SL. Find near, nearer or same sized spp.
IdentificationAll species in the genus Synodontis have a hardened head cap that has attached a process (humeral process) which is situated behind the gill opening and pointed towards the posterior. The dorsal fin and pectoral fins have a hardened first ray which is serrated. Caudal fin is always forked. There is one pair of maxillary barbels, sometimes having membranes and occasionally branched. The two pairs of mandibular barbels are often branched and can have nodes attached. The cone-shaped teeth in the upper jaw are short. S-shaped and movable in the lower jaw. These fish produce audible sounds when disturbed rubbing the base of the pectoral spine against the pectoral girdle.

At least 1/3 to 1/2 of all fins have a snow white edging. Long white barbles. Inky sheen to brownish body which bears a spotted pattern in younger fish. The contrast of this spotting diminishes with age.
SexingBoth sexes have identical colouration. Females grow slightly larger and tend to be plumper than males. Males have a 4-5 mm genital papilla near the anus.

Clearly one of the individuals is superior to the other & bosses the other at times. At 6 May 07 they are both around 47mm TL & still show the small dark spots ", (3) caudalis (k: 2), (4) synodont_fan, (5) Julie (k: 10), who also notes: "Appears to be two color types. One is more of a tan/light grey body and the other is a darker gray almost black body with a darker gray belly. Fish are distributed in 3 different 75 gallon tanks.", (6) derrickrscott, (7) unblinded (k: 4), who also notes: "Got the 1st in October of 2008.

One of the pair started appearing a bit tattered. I pulled it and it is recovering in a 55 gallon tank. I would like to add them to the 900 gallon sometime and see if they would spwan. Very cool, but shy. The fish I removed from the tub is now in the 900 awaiting its partner.2-2-2018: I moved the pair to the 1,000 gallon tank. They have been in this tank for proably a year now and are getting along okay. Fat and sassy.", (22) taylor1410, (23) shooter50014, (24) lasteeves, (25) Ostafrika-Barsche, (26) NeilB, (27) Long Barbels (k: 2), who also notes: "Have had for ~ a month. 3" specimen. One of the most active & least shy Synodontis in my collection and a voracious eater. Probably could hand feed. For a deep water Synodontis it surprised me to see him eating flakes upside down off surface.", (28) BiggNick916, (29) r7man (k: 2), (30) biggnick916, (31) Hsapsed (k: 2), (32) Slavi (k: 7).
