|General Remarks||W. Ralph Taylor (revised madtom catfishes in the 1960s) stabbed himself with each species of Noturus to try and discover which had the worst toxin. This dedicated research led him to the conclusion that this species, the tadpole madtom, was the worst.|
|Distribution||North America: Atlantic and Gulf Slope drainages from New Hampshire to Nueces River in Texas, USA; St. Lawrence-Great Lakes, Hudson Bay (Red River), and Mississippi River basins from Quebec to Saskatchewan in Canada and south to Gulf of Mexico in USA.

|IUCN Red List Category||Least Concern, range map and more is available on the IUCN species page. Last assessed 2012.|
|pH||6.2 - 7.0|
|Temperature||16.0-22.0°C or 60.8-71.6°F (Show species within this range)|
|Other Parameters||Good aeration but strong current unnecessary.|
|Feeding||Readily feeds on live and frozen foods. Madtoms appear to have difficulty in digesting earthworms and tubificid worms (even though they will gorge themselves when offered), and should not be fed these foods.
May also adapt to prepared foods in the aquarium.
|Furniture||A gravel bottom is not neccesary for this species. Provide a bottom of sand mixed with peat moss, PVC pipes, flat rocks and vegetation.|
|Compatibility||Suitable for a coldwater community tank. Ideal tankmates include small- to mid-sized North American native fishes such as shiners and darters.|
|Suggested Tankmates||Ideal tankmates include small to midsized North American native fishes such as darters and shiners.|
|Breeding||The northern populations spawn in May-August, although gravid females have been found in southern populations as early as April.
This species spawns in shelter and may use discarded containers for nesting sites. Both parents help to guard the nest and care for eggs (typically 93-150 in a clutch). The fish move over the egg mass in a shivering motion, with the anal fin in contact with the eggs, or take part of the egg mass into their mouths and spit it out.
|Breeding Reports||There is no breeding report.|
