Due to work carried out by
Reis, RE, P-Y Le Bail & JHA Mol, 2005. (New Arrangement
in the Synonymy of Megalechis Reis, 1997 (Siluriformes:
Callichthyidae). Copeia 2005: 678–682.) what
we thought of as Megalechis thoracata is
can be differentiated from the aforementioned
M. thoracata by having a band in its caudal whereas M.
thoracata has a spotted caudal fin. Aquarium
Care: Keeping this species is not too hard.
They can become quite boisterous in a community setup
with their digging and unsettling other fish at night
but as long as your other inhabitants are of a decent
size and are not "Neon Tetra size", as remember
this fish can get to nearly 8inchs in size and a small
1 inch tetra at night may be too much of temptation
to even the most docile of animals. The only time
they can get aggressive is if you have a pair and
they are in the throes of spawning as the males can
get quite tetchy and it is not unknown for a male
to kill the female in the quest to produce a family.
This does not happen all the time but best to keep
a look-out for any aggressive behavior. Reproduction:
This species is a bubblenester with the male building
it at the water surface. The female lays her eggs
in the nest and the male looks after them. This is
the point that you may have to take the female out
of the tank as they can get aggressive when guarding
Callichthys exaratus, C.
personatus, Hoplosternum personatus, H. thoracatum
surinamensis, Megalechis personata
Amazon and Orinoco River basins, as well as coastal
rivers of the Guianas and northern Brazil.
