Re: English is a crazy language
My brain tells me I ought to understand it, but all I can make out is a Geordie arguing with a laryngitic German over a bad telephone line. It's odd but it does seem as if understanding between languages can be asymmetric. Danish is closely related to Swedish, and danes I've talked to say they unde...

Re: Extremely shy corys and otos
To the best of my knowledge neither otos nor corys are particularly nocturnal animals. Certainly all I've had seemed to be active during the day. I second the suggestion to put some sort of free-swimming fish in the aquarium - some small tetras, or pehaps guppies, it doesn't really matter what as lo...

Re: English is a crazy language

I just can't seem to...

Re: English is a crazy language
Frankly, if I compare English with Spanish, Spanish is much easier in spelling and pronuncation --- But yes, English does have a lot of exceptions.

Re: algae eaters that suck the glass sides of the tank ?
The only effective way to keep the glass clean is by with an alga scraper. Personally I prefer the kind with a razorblade, but many prefer the magnetic ones, and either will do a much better job at keeping the glass clean than any alga-eating fish.

Re: Parasitic Worm affecting Megalechis thoracata
The worm is probably the roundworm Camallanus , and the recommended treatment is levamisole hydrochloride , although several other antihelminths have apparently worked.

What have you tried so far? Temperature, salt and metronidazole? Do you have access to formalin? Dosing 37% formalin to a concentration in the tank of 25-50 ppm and repeating this every other day for a week should kill any white spot parasites. Formalin does not appear to be excessively toxic to cat...

Re: Canthophrys gongota, Hamilton 1822
Somileptes is a junior synonym of Canthophrys, although it appears some indian authors either for some reason do not accept this, or are unaware of Kottelat (1998). Cf: Catalog of Fishes or Fishbase.

Re: oto catfish
It's a fish from the macrospilus/hoppei group. I am unsure how to separate the different species in that group; even, in fact, if they can be separated.
It's definitely not arnoldi, that is the same species as in the Cat-eLog is still called .

I don't see any reason to think this will not hold.
