Hi there.
Planiceps are wonderful catfish.
They can grow to well over 4 feet in length if looked after properly.
Unfortunately they tend to suffer quite badly with Bent snouts as a result of being kept in too small aquarimums.
Off all the big Pims they are very placid & generally appreciate peace & quite & slow moving calm tank mates - if any!
They can be skittish & have sudden bursts of speed.
Provide them with the biggest set up you can get them in, my 2 for example are currently in 6' x 4' x 3' heated Ponds, with tons of Aeration & massive filtration.
Although they will be move into even bigger accomodation as required.
Sandy base, Some big pices of wood & dim lighting completes the set up.
Mine a feed a mixture of Large Prawns, Earthworms & big white fish fillets - but only once, twice a week.
Hope that helps
Rob
