Description:
There has been some confusion on the identity of this
diminutive mothcat over the years. At one time
it was thought that it was a small Erethistini that
was first described by Professor Kottelat in 1983
as Erethistes maesotensis. However, E.
maesotensis proved to be a Hara type
not an Erethistes type, due to it having the serrae
on the anterior edge of the pectoral spine antrosely
directed and not divergent. It has since been diagnosed
that E. maesotensis is Erethistes
(Hara) filamentosus (Ng & Kottelat,
2007). Yet the Erethistini pictured were the type
that was being seen in our local fish stores under
a variety of trade names such as burmese mini
mouth cats and burmese rock cats. It was assumed that
these were Erethistes maesotensis and therefore
the synonym of Hara maesotensis and again
as later Hara filamentosa. However these
small Erethistini have proved to be Erithistes
minusculus (Ng & Kottelat, 2007) and
the differences between these two when Erithistes
filamentosus and Erithistes minusculus
are juveniles of comparable size, is subtle and misidentification
therefore can be forgiven. In profile Erithistes
minusculus has a curvature to its head whereas
in Erithistes filamentosus the profile is
more angular. Aquarium Care: A tank
with a sandy bottom and rounded stones and pebbles
with a good water flow as befits an asian hillstream
setup. Good water quality is a must for this family.
Keep the water temperature on the cool side of a tropical
aquarium. Tank mates such as the zebra danio (Brachydanio
rerio) and asian fish such as Rasboras of the
same small size will make good tankmates. Diet:
Prefers live foods such as bloodworm, grindle worm,
daphnia and Artemia naupli. Etymology:
Erithistes, Etymology not explained, presumably
erethizon, porcupine and–istes, adjectival suffix,
i.e., porcupine-like, referring to strong and serrated
dorsal and pectoral-fin spines.The species
epithet minusculus meaning
'minute',
known for its small size. Remarks:
You will still find this species on some online searches
as Hara minuscula.
