Ok!
1) Hara jerdoni is in the wrong family of catfish should be Erethistidae rather than Sisoridae (i did pm a mod about this yesterday so not so pressing i would guess, CFC i think it was)
2) The picture on the Rubbernose pleco profile is not Chaetostoma milesi more than likely is Chaetostoma cf. thomsoni.
3) Most important things when keeping this pleco are heavy current, highly oxygenated water and cooler temps (20-23(68-74)) oppsoed to the higher temps quoted there (some mention is made later on in profile, but original info is incorrect)
4) Sexing these fish is done by comparing the pelvic fins rather than the dorsal fin as quoted (males have larger compared to female)
5) Clown Plecos are regularly bred in captivity, and in terms of sexing them 'Like all members of the genus, males grow elongated interopercular odontodes during the breeding season. Males develop noticeable odontodes along the dorsum as well.' (source www.planetcatfish.com) certainly not impossible to distinguish, as anyone who has seen dorsal odontodes on panaquolos sp. will tell you.
6) Ancistrus dolichopterus is still being quoted as the scientific name for Britlenose, yet the photo displays Ancistrus sp.3 (regarded as 'common bristlenose' in pet trade)
i was going to add these to the individual threads/profiles but i notice that we are asked not to do that which is why i guess things like the sci. name for Bn's hasn't been changed on the back of Lisa's post.
