Tank 18: Hoplias curupira Wolf Fish tank

Hoplias microlepis Wolf Fish tank

This tank houses a Black Wolf Fish, Hoplias curupira, a highly aggressive predatory fish - hence he is kept alone! This fish is so aggressive he attacks the siphon pipe during water changes.

Heating Heated room
Lighting Low - fluorescent room lighting only.
Substrate Thin layer of aquarium sand.
Decor Bogwood
Background 3-D effect artificial background
Water parameters Temp=26oC ; pH=6.8-7.0 ; GH=3 ; KH=2
30% water change every week.

This is one of six tanks that I have with built-in internal filtration units. I specified the design for these and had them built into the tank at the time of manufacture. They are efficient and very low maintenance. They are also separated from the main tank, so large fish cannot interfere with the filter in any way, and there is space to put a heater in the initial filter chamber too.
The tank itself is wide (front-to-back), but not very high - ideal for raising mainly bottom-dwelling predators which need plenty of floor space, but in some cases need to be able to reach the surface easily to gulp air.
