The third image specimens
were collected by image contributor and Swiss aquarist,
Yann Fulliquet, in the Rio Negro near the town
of Barcelos, Brazil. 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 once thought of as Megalechis
thoracata is
now Megalechis picta and can be differentiated from
the aforementioned 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 7inchs 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
the nest.
