|Cat-eLog Data Sheet|
|Scientific Name||Synodontis eupterus Boulenger, 1901|
|Common Name(s)||Featherfin Syno|
Featherfin Squeaker, Fjäderfenssynodontis (Sweden)
|Type Locality||Mouth of Lake No, White Nile, Sudan.|
|Synonym(s)||Synodontis euptera, Synodontis macrepipterus|
|Pronunciation||sin oh don tiss - you TERR ahh|
|Etymology||Synodontis: From the Greek syn, meaning together, and odontos, meaning tooth; in reference to the closely-spaced lower jaw teeth. This specific epithet literally means beautiful (eu-=beautiful,good) wing (pteron=wing).|
|Size||222mm or 8.7" SL. Find near, nearer or same sized spp.|
|Identification||All 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.|
Juvenile colouration is quite different from that of the adult. The change begins when the fish reach about 40mm and gradually continues until they pass the 100mm mark.
|Sexing||First lay the fish in your hand with its head toward your palm and the tail toward your fingers. Hold the dorsal spine between your middle and ring finger so the fish is belly up and you won't get stuck (Which by the way, hurts like crazy!). The genital pore is in a small furrow of tissue (in healthy fish) and will be obstructed by the pelvic fins. Pull down on the tail gently to arch the fishes spine and the pelvic fins will stand and the furrow open to display the genital pore and the anus of the fish. The male has a somewhat ridged genital papillae on which the spermatoduct is on the back side, facing the tail fin. A gravid female will also show an extended papillae but the oviduct is on the ventral side of the papillae (And may also show a little redness if really gravid). A thin or emaciated female will have just two pink pores, the oviduct and the anus.|

|IUCN Red List Status||Least Concern|
|pH||5.6 - 7.5|
|Temperature||22.0-26.0°C or 71.6-78.8°F (Show others within this range)|
|Feeding||Bloodworm, Sinking Catfish Pellets, Doromin|
|Furniture||Lots of rock caves and bogwood. Likes open spaces to patrol in the twilight / dark. Ensure the fish do not hide near a heater; they can burn themselves which leaves a nasty scar.|
|Compatibility||Peaceful. Can be kept singly or in groups given adequate refuge for each individual. A large multi-branched piece of bogwood is ideal.|
|Suggested Tankmates||Most medium or large community fish. Although commonly available as such, not a good species for the small community tank. Anything smaller than 3foot / 1 meter long, go for Synodontis nigriventris instead.|

They are so cool! They usually stay in my log with my Rainbow Shark til 9 a.m. then they come out and explore the tank til about 10:30 when the sunlight hits the tank and they duck back into the log til around 5 p.m. I feed about quarter til but they seem to like to wait for the pellets to dissolve some. They stay out about til midnight.
To be honest I wanted Pictus, but I stumbled upon a situation where I could get some free fish and the Pictus looked awful, but these little guys had been there for about a week and were still looking good. Walmart had advertised them as Lace Catfish (They're now calling some Orange Squeakers Lace cats. Haha!) I normally avoid Walmart fish but needed a Molly for school, but since they were still alive I figured they were pretty healthy. I've had them two weeks now and they've grown a 1/4 of an inch. In that time, I have become a fan. They don't swim around the tank constantly, in fact they seem to prefer hanging out in/on some of my false plants (I have a mix of life and fake).
I have to say that the hardest thing to get used to is that they will sometimes lay upside down under the plant leaves. Initially, I thought they were dying and stuck my hand in there to make sure that was not the case. Now I'm much more accustom to it and I think these quirks add the draw of this breed.
I'm currently working on getting everything set up for a 55 gallon tank. Since this tank will be staying at my school's science department (can't have it in the dorm) for the next four years, I'm working to create a habitat that will be a cross between their natural African rivers and my shark's Aisan river basins. I should have this tank started on the cycling process no later than the end of January. :)", (184) Crazysosa, who also notes: "Hangs Out Vertically most Often", (185) Maccus (k: 6), who also notes: "List of mysteries:

He gets really excited every time his tank is cleaned and checks out the placement of everything, zooms around what looks like very happily, checking everything out. He loves his rock cave. Now that we know what kind of catfish he is, we know that we'll eventually have to upgrade the size of his tank. Presently it's 10 gallon. His tankmates are one Siamese Fighting Fish (who keeps clear of Bob who is the boss) and 12 neons. Bob is pretty peaceful with the other fish, but he does show the Siamese Fighting Fish who's boss every once in a while by occasionally chasing him away (but he doesn't bite at or nibble the other fish).
