With the increased interest in Natives over the past decade a great
many of our native species are being rediscovered as an aquarium
species.
Not since the 1920's have so many people inquired about and begun
keeping natives. The writings of people like John Quinn ( A Netfull of
Natives) and Larry Page ( Petersons Field Guide to North American Fresh
Water Fish ) and the many excellent State books have helped to get out
the word and people are listening !
Many an avid aquarist, who is unfamiliar with our natives is
surprised to learn that our own humble Natives have intense color,
interesting temperament and a variety of body types that surpasses many
tropicals. When you combine these with their ease of care natives are a
class of fish every aquarist should consider.
Not surprisingly the sunfishes are usually the first Native fish
people keep. The sheer number and types of sunfish make them an excellent
first native. They are easily collected with hook and line or dipnet or
seine. Not all states allow netting of Sunfish so check out your local laws
for the who's and what's of your area.
As a rule they are very durable, tolerant of most anything and
tough as nails. In temperament they are usually one or two notches below
an Oscar (Aggressive but not completely intolerant of other fish). They
range from the gentle Black Banded Sunfish (Ennecthaseus Chatedon) whose
graceful fins, angel like coloring, slow movements and delicate
temperament are a hit with the Discus crowd. To the positively brutal Green
Sunfish (Lepomis Cyanellus) whose large mouth and pugnacious attitude make
the Oscar lover in us all smile!
The Central Longear is in my opinion the best sunfish for the
novice to keep. It's combination of color,manageable size (under 6
inches in most cases) and personable mid range temperament make it
the ideal first fish for the aquarist new to native fish. Its overall
body shape varies from region to region and sub species to sub species.
It can go from long and angular to rounded and slightly reminiscent of
the Discus shape. However it is its life colors, that make this fish
nothing short of spectacular and the must see of the Sunfish family.
Here is how Bill Plieger describes them in his "Fishes of Missouri" pg.
268.
"Life Colors: Back and sides blue-green speckled with yellow and
emerald; belly yellow and orange. Side of head olive or light orange with
emerald-blue vermiculations. ear flap black, often with a narrow white
border. Fins without prominent spots or blotches. Breeding males have all
colors more intense, with the under surface of the head and belly bright
orange-red."
With that definition you can see why I am confident to place them in
any aquarium contest in any freshwater category.
When finally in the aquarium Longear's quickly adapt to captivity and
will take in a variety of foods. I do mean VARIETY, I have seen them fed
everything from flake food to cat chow, including all the standard frozen
and live foods.
They are a natural for those who keep garden ponds and don't want to
keep Koi or any of the more standard species of pond fish. They will
thrive in an outdoor pond and can often be over wintered with no ill
effects. They will of course spawn in such an environment and are a
very low maintenance fish. They thrive on insects that fall in the water
and mosquito larvae.
I have even known people who have kept ponds outside near a bug
zapper. Their Longears have thrived on the near misses and half shocked
insects! Now that's an easy to care for fish!
If you are interested in aquarium breeding this fascinating
sunfish it's a snap. They behave in a similar fashion to many tropicals in
that the male will make a nest attract a female and spawn on the site. He
will then remain on site guarding the eggs and fry until they become
free swimming.
The Longear Sunfish's must be excellent parents. One several
occasions while observing nesting sites. I have seen various types of
darters and shiners rushing in when the male Longear is distracted and
laying their own clutch of eggs beside those of the Longear. The eggs are
then cared for by the Longear male along with his own. He is of course none
the wiser and the survival rate of the other species shoots up
dramatically.
In the laboratory with the proper diet, a temperature of 77 F., and an
extended photo period they have spawned every 10-14 days for over a year!
Now that is prolific, of course in the wild those conditions are usually only
met a few days or weeks out of the year. So therefore the natural
reproduction rate is much lower.
Here's What Dr. George Becker in his classic state book "Fishes of
Wisconsin page 839" says about the Longear sunfish.
"The Longear sunfish adjusts well to captivity. It is not susceptible
to injury from handling is not unduly aggressive and appears to be a
promising species for use as a laboratory test fish (Ward and Irwin 1961,
W.E.. Smith 1975). In the laboratory, W.E,.Smith was able to get the
species to spawn, to raise the young to maturity in 22 weeks (males 10-12
cm, females 7-9 cm.) and to produce successive generations under conditions
of long photoperiod and a water temperature of 25 degrees C (77F). The
adults continued to spawn with regularity every 6-10 days for 14 months."
With that information even an inexperienced aquarist has a good shot
at successfully spawning these gems.
I have found that the Longears from Missouri and Arkansas are
the most colorful and make the best stock to start from. However You may
find a different local strain that catches your eye with just the right
color and size mix for you. If so, go for it. That is one of the great joys
of collecting is finding that local strain that catches your eye. Let me
know what you find!
One of the nicer things about the Central Longear is its abundance
and extensive range. If you live in the eastern third of this country
from Canada to Florida you are in Longear country! So collection of suitable
specimens is not terribly difficult. They are easy to collect from a
suitable sight with seine, hook and worm or dry fly. When you get one
they are easy to identify. Their unmistakable ear flap is up to 1/3 or
their body length in size and black as tar. I strongly recommend taking
individuals under 4 inches as at that size they seem to adapt best to
domestic life.
If you like the Cichlid family I promise you,you'll love the
Central Longear. With his twisting palette of colors he is as Colorful
as any Cichlid and is as personable as a fish can get .They are as easy to
care for as any fish I've ever kept. Why once I left some in a 5
gallon bucket after a collecting trip for over a week only to find a male
guarding a fresh batch of eggs! Mine commonly eat out of my hand and will
allow me to pick them up with my hand! So if you thinking about going Native
I have just the fish for you.
If you are interested in keeping Native fish in the aquarium I
recommend you start with your local Department of Natural Resources or your
local North American Native Fish Association regional chairperson (I am
one). I can be reached at 2213 Prytania Circle Navarre Florida 32566 if
you need further information.
