The classification of species
within the Ariidae is arguably the most poorly resolved of any catfish
family. In recent years, there have been three independent attempts
to examine the phylogeny of the family (Marceniuk, 2003; Kailola,
2004; and Betancur et al., 2004) and produce classifications that
reflect the resulting phylogenetic hypotheses (see Ferraris 2007).
Listed in this paper as Ariopsis seemanni. From Marceniuk
et al 2007, the species of Sciades can be differentiated
from all other genera of the Ariidae by the combination of the following
exclusive (1 to 5) and shared (6 to 8) characters: (1) medial groove
of neurocranium delimited mostly or exclusively by frontal bones
(fig. 90); (2) temporal fossa very reduced or entirely closed during
ontogenetic development (fig. 90) (with exception of Sciades
leptaspis); (3) otic capsules little developed; (4) space between
transcapular process and otic capsule very wide; (5) subvertebral
process indistinct or little differentiated; (6) posterior cranial
fontanel absent (fig. 90) (with exception of Sciades platypogon
and shared with Batrachocephalus); (7) epiphyseal bar indistinct
(with exception of Sciades platypogon and shared with Batrachocephalus);
(8) exoccipital posterior process sutured to Muller’s ramus
(with exception of Sciades platypogon and shared with Potamarius
izabalensis). Aquarium Care: Small specimens
are not a problem in aquaria but when they get bigger they get restless
and will require a larger tank for swimming space and also a requirement
for added salt as they grow into adulthood. Provide caves for hiding,
a dark substrate and low lighting. Will need good filtration with
a swift current. Diet: Omnivore: insect larvae,
frozen foods such as mosquito larvae, tubifex and bloodworm. Tablet
and flake foods are also taken. |
