|Cat-eLog Data Sheet|
|Scientific Name||Kryptopterus vitreolus Ng & Kottelat, 2013|
|Common Name(s)||Glass Catfish
Asian Glass Catfish, Indischer Glaswels (Germany), Indisk Glasmal (Sweden), Phantom Catfish
|Type Locality||Thailand: Trat Province, Amphoe Khao Saming|
|Pronunciation||Kreep top ter russ - vee TREE oh lurs|
|Etymology||Kryptopterus: From the Greek kryptos, meaning hidden and pteryx, meaning fin; in reference to the reduced or absent dorsal fin of this group of fishes. From the diminutive form of the Latin adjective vitreus, meaning of glass, in reference to the transparent appearance of this species in life (which gives this species its common name of glass catfish).|
|Size||80mm (3.1") SL. Find near, nearer or same sized spp.|
|Identification||Sometimes - the African Glass Cat, Parailia pellucida - is labelled as the Glass Cat, so always keep your eyes peeled when you look at a tank of these fish for sale. We have labelled this fish with a scientific name different from that you find in most hobbyist books. It appears that the glass catfish has been misidentified for a long time now as Kryptopterus bicirrhis, this fish grows much larger (up to 245mm) and has more rays in its anal fin. It is quite possible that, at some point in the last 30 years or so, K. bicirrhis was the fish imported into the aquatic trade as the Glass Catfish.|
|Distribution||Known from the short, coastal drainages in peninsular Thailand debouching into the Gulf of Thailand south of the Isthmus of Kra (from about 8°38'N to 6°2'N), as well as similar rivers draining the southeastern face of the Khao Banthat (Cardamom) Mountains in southeastern Thailand.

|pH||5.5 - 6.5|
|Temperature||21.0-26.0°C or 69.8-78.8°F (Show others within this range)|
|Other Parameters||Slow moving water providing areas of current and areas of still water. This fish rests in still water and stalks in gentle current.|
|Feeding||Will usually take prepared foods especially if moved by a current. Likes live brine shrimp and larger established fish relish bloodworm.|
|Furniture||Plants are necessary to make this fish feel at home. Floating plants that diffuse overhead light help but are not mandatory. Open swimming space is required, as this fish favours swimming freely at feeding.|
|Compatibility||Peaceful, will eat very small fry, but otherwise harmless.|
|Suggested Tankmates||Keep in a shoal of at least four but preferably six or more individuals. Such a shoal of glass catfish will do well with small tetras, rasboras or danios. Provided its tankmates are not too boisterous this fish will do well in well planted community aquaria.|
|Breeding||Unreported within the confines of four glass walls although reportedly accomplished commercially in Asia - details are unavailable.|

|Registered Keepers||(1) Jools, (2) snowball (k: 25), who also notes: "They split up into two groups during the day, both sheltering under overhang wood. At night they all school along the front of the tank in the current. I feed them at night, but they will come out during the day when they smell food.", (3) kcmt01, (4) Persephone, (5) Moontanman, (6) adimeatatime (k: 10), (7) gage, (8) H (k: 5), (9) Richie Hell, (10) Marsdinho, (11) Blairc (k: 6), who also notes: "These timid Cats are very good eaters, and can be fed on a diet of flakes, frozen and live food. They are extremely sensitive to changes in water conditions, and will go white when stressed. These fish enjoy having peaceful tankmates and a good plant. These Catfish are my favourite fish, and have been through the thick and thin of my fishkeeping career.", (12) Igowoof, (13) artemis1, (14) spot86t, (15) pleco_keepin_bear, (16) bang (k: 2), (17) mouseninja (k: 3), (18) lene.keiserud, (19) Plecofanatic1989 (k: 3), (20) nooneknows (k: 6), (21) c arri10 (k: 5), (22) theonetruepath (k: 2), (23) fraggle (k: 5), (24) kvnbyl (p: 2, k: 9), (25) jb92 (k: 3), (26) Plunt, (27) loachy_406 (k: 4), who also notes: "They are quite active when the light is off, but otherwise they stick to the shade, or in the hollow rock.", (28) ZedMuir, (29) mini-fée, (30) mante-religieuse (k: 6), who also notes: "2 died from ICH 2 weeks after I got them.
6 are perfectly healthy", (31) AimsPink, (32) griffl, who also notes: "One expired on 9-4-08.

Some will frozen bloodworms out of my hands and some have even been slightly territorial towards other species.", (49) coelacanth, (50) ocnluv13 (k: 2), (51) bronzefry, (52) L number Banana (k: 3), who also notes: "Can be hand fed with frozen brine shrimp, they tickle your palm :-)
Very cool fish to watch, sometimes bicker among themselves and will often chase larger tetras away from food.
Update winter 2012: lost three when lid broke and they jumped out.", (53) judeblackburn (k: 6), (54) roadkingray, (55) kouen (k: 9), (56) djechoskittykat, (57) Hansen (k: 2), (58) Dee (k: 5), (59) Grimfilth (k: 7), (60) Dalek Tzet (k: 2), who also notes: "I cannot get groups of these to thrive, they always whittle down to one or two, who are fine for months. add another, instant death. I can't win. They like to glare balefully from under plants, eat anything.", (61) milutin (p: 2), (62) Anthonyck (k: 5), who also notes: "Lost one of original six early on. Remaining species are doing well, though a couple are growing much more rapidly than others. Inconsistent shyness; seem very sensitive to any changes, water cleaning, noises, etc.
June 2012: lost one when moving tank. Did not get water temp balanced quickly enough, and a few kryptopterus seemed to "sink" because of the temperature change. One did not survive this disturbance; all others recovered completely.", (63) Quo (k: 5), (64) arapaimag (k: 6), (65) browny85, (66) fleshwound (p: 2, k: 3), (67) Apostolis (k: 2), (68) indiCa, (69) Sfamnun (k: 9), (70) AvengedKombat, (71) linuxrulesusa (k: 2), (72) 000, (73) in_the_seance (k: 8), (74) DKcincy (k: 5), who also notes: "These guys went nuts when i offered them frozen brine shrimp", (75) Rebah, (76) Sean B, (77) crazy4bettas (k: 6), (78) dmcat (k: 7), (79) Valb68 (k: 6), (80) glasscats, (81) VickyEll7 (k: 4), (82) dpm1 (k: 5), who also notes: "Kept in a mixed community where they are pretty much the biggest fish. They hover in the rear but aren't shy or skittish including hand feeding, unmoving during maintenance, and will come forward as soon as the lights dim (and sometimes before, especially if feeding). Can be sexed when carrying eggs but other times almost impossible. Unfortunately didn't see any actual breeding or egg laying.", (83) bekateen (k: 5).
