Scientific Name | Hemiancistrus sp. (L128) , 1993 |
Common Names | L128, Blue Phantom Pleco Blå Fantom-sugemalle (Danish) |
Etymology | Greek, hemi = the half. While the Greek, agkistron = hook, is thought to be the root of the term ancistrus, hemiancistrus can be taken to mean that these species have a part (not exactly HALF) of the features of the genus Ancistrus, but not ALL of the features. |

Feeding | The fish is omnivorous and easy to feed. Although and effective algae eater, it should be given a varied diet of prepared foods. User data. |
Furniture | Lots of vertical stonework and rounded boulders. Bogwood and plants are not necessary. Water current should be at its strongest over cracks and crevices in the rocks where the fish will live. |
Compatibility | Not quite as hardy as L200 and appears to take slightly more effort on the part of the aquarist to acclimatize. It will live in calmer water should you wish to keep this fish in a medium sized community setup. |
Suggested Tankmates | This fish is a good pleco for a community tank despite it's natural habitat in rapids as it will adapt to less hectic water conditions. If you do want to try faster water, Semaprochilodus characins and silver dollars of various types are a good choice for mid-water companions. |
Breeding | Have been spawned in aquarium. Male guards eggs in similar way to most other Hypostominae subfamily fishes. |
