General: The
longear sunfish is highly variable in color throughout its range, and
has a pretty good size range as well, from the small Northern longear at
5 ½”, to the largest of the subspecies, the Central longear at 9” max.
They’re natural range goes from as far south as Florida, all the way up
to Quebec, Canada. These guys also tend to like streams more than other
sunfish.

Tank Size:
For one of the smaller subspecies, such as the
Northern, a 30 gallon could work for one or a pair. More than one or a
pair or trio of the larger species need more like a 55g. Sunfish like
their space.

Relatives: As for other sunfish species, many of them are
commonly known to fishermen and children that have gone fishin’ with the
parents. There’s bluegill, green sunfish, warmouth, red-ear (shellcracker),
bantam, pumpkinseed, redbreast, spotted, redspotted, dollar, and
orangespotted sunfish. That’s just one genus. I don’t think I’ll go
into any others. They all range in size from 3” bantam sunfish to 13”
red-ears, also known as shellcrackers by fishermen.

Here is a small warmouth (Lepomis gulosis) with a green sunfish (Lepomis
cyanellus) in the back. Same genus as the longear sunfish.
Food: To begin with, you’ll probably have to feed your
longear something natural, like earthworms or feeder minnows (if they
can fit in its mouth). After it associates you with food, it may start
taking small pellets, like Hikari Soft Pellets made for cichlids. Young
ones can be trained to dry food easier than older ones, but you can
teach an old fish new tricks. If you feed the rosy reds you buy at the
store, be sure to quarantine for a week and feed high-quality flakes.
Many of those fish carry parasites and diseases from poor water quality
and cramped conditions. Or you could buy worms used for bait or go dig
up your own. Just be sure to collect your worms from places that haven’t
been infected with pesticides.

Growth: If fed well and kept at temps in the 75+ range,
they can grow up to an inch a month. This will also depend on
competition in the tank. Of two longears kept in the same tank, one will
likely become dominant and be the one that gets most of the food,
therefore growing much faster.
Sexing: After they hit about 3 inches, sexing these fish is pretty
straight-forward. Males get much more colorful and have longer “ear
flaps,” the black flap connected to the gill cover.

Here is another picture of one of my male longears at about 3”.
Breeding: Although I have not yet bred them, they breed like
all other sunfish, in that the male will construct a bowl-shaped nest
and will court females into the nest to lay eggs. Male sunfish guard the
young until 2 days after they become free swimming. If you want to breed
them in captivity, separate the male and female for conditioning and
feed them live foods and keep them at a higher temperature than usual,
around 75-78F. When the female becomes fat with eggs in about 2 weeks or
so, add her to the male’s tank and breeding should take place.

More info: If you want to learn more about sunfish or other
native species, visit the Native Fish Conservancy at
www.nativefish.org for some great articles, or NANFA at
www.nanfa.org, which has even more great articles. NANFA also has a
forum for native fish keepers, at
www.forum.nanfa.org.
Last words: Why keep them? They’re easy to keep, beautiful, and can
be found locally. Just make sure you check your game fish laws to be
sure you aren’t taking under-sized or illegally collected fish. In most
states, these are considered game fish, and must be caught with a hook
and line to be kept legally.
