hello guys
i found this thing in fish tank ( i suspect its a diatom ) :
is it a diatom , why its so different from the other familiar looking diatoms
i mean.. it looks evil .
is this a diatom ?
Re: is this a diatom ?
Not like any diatom I have ever seen. Looks like half of a hard shell amoeba.
Re: is this a diatom ?
Hello Mr. Micro,
it is a testate amoeba, definitely a Centropyxis species most probably C. aculeata.
Cheers,
Hans

Re: is this a diatom ?
I know I've seen the occasional little discose amoeba in aquarium debris, somewhat Mayorella- or Korotnevella-like, and in one case lots of the heliozoans Actinophrys among algae films. But whether or not they are more common, testate amoebae are generally more conspicuous. A discose amoeba often looks like just a bit of debris until you watch it for a while; whereas shells like this are not only recognizable, but also endure beyond the living amoeba so can accumulate over time.
