Maintenance:

    Bottom opportunistic feeder. Dominating territorial species of plec. Best not kept with other plecs at all, they could easily be attacked.due to their size should be kept in big roomy tank.larger but not aggressive mid to top swimming fish tank mates should be fine... water should be kept pristine with water changes, large driftwood, bogwood and rocks, no plantings as they will be uprooted. Sand is the best substrate for them. Good filtration. Like fast moving water if possible. Need 125gal tank min. Not a fussy eater--fruit, vegetables, pellets and bits of fish, algae wafers and live foods. Feed 2x's a daily.


Biotope:
    Sand and large bogwood, driftwood and rocks

Breeding:

    Although it has been reported to have bred in the home aquarium details are not available. When it has been confirmed I will list it here.


Conclusion:

    These fish are very interesting to keep. A bigger tank is always advised. Plecos are beautiful with their forked tail and brilliant white spots on black, as adults they are shiny jet black. Most active at night. Pretty peaceful but will be territorial so other catfish and plecos are not advised. This fish is a bit challenging to keep in cycled tank, they are hard to find and expensive to buy. Good fish for the experienced fish keeper. They live about 16 years... great addition to that big tank with large middle to top of tank fish. Attractive and eye catching pleco.

I owned this fish for 4 months. Bought it from my LFS as a 1" juvenile for $35. In my 30 gal tank, it was fun to watch, not shy at all. It loves cucumbers (cut in half) and was actually active day & night. After 4 months (it grew to about 3") it became much more aggressive and territorial. So much so that it killed 2 of my RCS and 2 Kuhli loaches. I ended up returning it to my LFS, swapping for a more peaceful albino bushynose. A beautiful and fun fish to watch with the caveat that it needs bigger tanks and can grow up to a few feet eventually.
