|Satanoperca daemon is relatively common in the trade, but often does poorly in aquaria. It is a blackwater fish and therefore requires somewhat extreme water chemistry parameters (outlined above). In addition, it is very sensitive to degraded water quality, so the difficultly is in providing enough good quality water of the appropriate chemistry. This species is very sensitive to HLLE (Head and Lateral Line Erosion) and can be affected by "Neotropical Bloat" as well - a condition not easily treated.|
The diet of S. daemon should follow that of the other species of spotted demonfish, small, easily chewed food items fed several times a day. Frozen brineshrimp, frozen bloodworms are good staples to use. Flakes and soaked pellets can also be included in the diet. Success has been achieved with using a green pea/krill based gelatin food.
Satanoperca daemon is a "modified" substrate spawner in that it covers over the eggs with woody debris. Newly hatched larvae are left uncovered. Unfortunately, it has rarely been bred in the aquarium and successful raising of the fry is even rarer than that.
This is not a fish for the new hobbyist.
