mudminnows are considered cool water species, but here in the marsh they can
be found in water hot enough to take a bath in. Centrals are found in
Reelfoot Lake in Tennessee, and Easterns to northern Florida. They also are
found in current to stagnant waters, but prefer slower to still waters. They
prefer lower lighting, but once acclimated tolerate bright lighting. They
are more than adaptable species.

Until trained, they eat only live moving foods. They care little about their
decor, but like something to hide under or in. If the substrate is fine
enough they will bury into it, but that is usually not what they do.
> 6a; Does it have an interesting color?
Male centrals (Umbra limi) in breeding dress are spectacular and get short
changed in most all publications describing this fish. Certain populations
are attractive no matter what, male or female, breeding or not.
> 6c; Does it have an interesting behavior?
Normally stationary, but when hunting, attacking food it is quite unique (
aside from pike which it acts like). They also spar with each other and
other species with gill flaring and back arching. Normally no damage to any
fish from this display of aggression.
> 6d; Does it have an interesting history?
You would have to ask the fish itself.

In my opinion, it is one of the neatest fish to keep. Especially if you ever
wanted to keep a pike or pickerel, but did not want the grocery bill one of
these fish rings up, or the size of tank one should have for an Esox.

Unlikely to spawn without sufficient attempts to replicate a wintering
period. Drop in temps more important than photoperiod I would guess. Highly
unorthodox, but putting them in a refrigerator for over a month might do it.
All that said, this fish is really a swamp dwelling species, and would need
living food items to meet its nutritional needs , unless you are lucky to
get one to take prepared foods ( which dace can often teach them with
patience). To get them to spawn a wintering period is most assuredly a must.
