karigupi,
he/she eats, well, anything really! i feed him lancefish, prawns, cockles and bloodworm.
erm it will get to around 10 inch so i should think a 4 foot tank would be sufficient, it is in a tank with gravel now, in the wild their substrate is made up of anything from mud to rotted leaves so i think anything would do!
in its short period with other fish it was fine, it was even with my little babe albino senegal bichirs for a day or 2! i wouldnt reccomend putting it with fish smaller than a few inch's though.
its kept at around 25 celcius but supposidly ok anywere inbetween 22 and 28 celcius.
it would need a few hiding spaces, probably appreciate some plants and a bit of open space, it is in a tank now with pea gravel and a few rocks as its hopefully just a temporary home!
erm lancaster is near preston you know were that is? or just north of blackpool!
northants? just north of london? think it would need posting!
could find out costs if you decide you want it.
