so please answer my questions and, just so everyone knows these are freshwater eels some people may think im talking about fire coral eels but these are fresh waterI have two young fire eels i would love some tips and advice?
The Fire Eel is a nocturnal predator, and part of the Mastacembelidae family, also referred to as the Spiny Eel family. Members of this family are not true eels. They are elongated, tropical, freshwater fish that have numerous spines preceding the dorsal fin.





Best suited for a larger aquarium, a soft substrate is necessary for this fish. The Fire Eel will often dig in the substrate and bury itself; this may uproot plants and rearrange decorations. A tight lid should be used for any long, slender fish, as they will often try to escape from the aquarium. The Fire Eel should be kept with fish of similar size or larger, and will not tolerate its own kind.





A carnivore, live foods such as earthworms and black worms should be fed to the Fire Eel. Prepared tablet foods as well as krill and ocean plankton may eventually be accepted.
