The Orangethroat Darter as
an (Etheostoma spectabile) Aquarium
Species Robert Rice
Most
people are completely unaware that darters exist. Darters are thosesmall mystery
fishes that one occasionally sees literally darting around theedges of streams.
Unless you are unusually perceptive or aggressive you haveprobably just not
noticed them.
All darters are in the perch family, and as a general rule
have no swimbladder and thus stay on the bottom feeding and living out
theirlives. Darters display a surprising range of color and body types and
asgeneral rule make a fascinating aquarium pet. They display a degree of
sexualdimorphism with the males being the brighter and more aggressive of
thesexes. Which makes them all the more interesting!
The main
consideration is temperature requirements as many species ofdarters must have
cold water to thrive. The Orangethroat darter, in myexperience, is the
exception. I have collected them in waters as high as 81degrees F and have kept
them in community tanks with great success.
There is a large genetic
gradient range in the Orangethroat darter in itssize, color and tolerance to
domestic life. So keep in mind your success willdepend to a large degree on the
stock you begin with. Therefore collect froma site similar to the aquarium in
water quality and tempature.
The book Fishes of Missouri pg. 320
by Pflieger describes theorange throat darter as follows. "A moderately stout
darter (1.2 - 2.5inches) with 6-10 indistinct dark cross bars on the back. Sides
oftenprominently streaked by dark horizontal bars......Its life colors are
asfollows, back mottled yellowish-brown with in distinctive dark color
crossbars. Sides lighter brown, often with narrow blue green vertical bars
bestdeveloped towards the tail. Breeding males VERY brilliantly colored
sideswith a series of blue green bars alternating with brick red bars.
Gillmembranes bright orange (thus the name orange throat) with remainder of
undersurface of head blue green. The fins are variously banded and spotted by
bluegreen and red."
With that generic description I hope you can begin to
imagine the beautythis little fish possesses. When you combine his looks with
his lack ofshyness you can see why I place him first on my list of darters !
Often otherdarters cower and are hidden from the eye. The Orangethroat is out
for all tosee , fighting for food and territory in a fascinating way. Why more
thanonce I've seen a Orangethroat rise to the top and steal a morsel of food
froma fish 5 times his size!
Now with the basic definitions out of the
way I can share with you how Itreat my darters . When wild caught I immediately
place them in a tank with afew feeder guppies by observation they quickly take
eating frozen food of allvarieties . Mine seem to prefer blood worms but will
take most anything evenflake food . Once I am confident they are eating properly
and appear to bethriving. I place them in their permanent homes, one of my large
communitytanks. Then comes the most fascinating part for me , the waiting to see
whichdarters posses the right mix of temperament and color and tolerance
todomestic life to make it to the brood stock category!
When I have
identified likely candidates I pull them aside and "winterthem over" in an area
that holds a temperature of 60 degrees or less over thewinter. In my case that
is the laundry room of my walkout basement, forothers that might be your
basement proper or your garage. Then begin toobserve because in no time ( 3-5
weeks) you are going to see boldly coloredmales establish territories and court
females. I put 2 trios in a 20 gallontank with some steady current and keep my
eyes open. Sooner or later the malewill coax a female into his cave (either
rocks or small flower pots) and theywill spawn, laying several hundred eggs.
These eggs will adhere to whateverthey hit. Here's the catch you must watch
carefully your fish or they willeat their eggs ! As soon as I realize a spawn
has occurred parents and eggsare separated.
In 7- 10 days you will notice
the fry appearing. . They are a very durablefry and generally easy to take care
of. They will grow fast if given properfood and care. Mine will often take live
brine or infusoria early (6 x aday!) then frozen baby brine (3-4x a day) then
finally blood worms (2x aday).
