Banggai Cardinalfish
Tank Conditions:
The Minimum Tank size should be at least 30 Gallons but I think a 10 *Could* work.
74 - 82 Degrees F / PH should be 8.1 - 8.4 / SG: 1.020 - 1.025 / Lifespan: 5+ Years / Cost: $13 - $30 / They get about 3 inches
Behavior:
They seem just float in place making quick dart-like movements. They are also reef safe and do not eat inverts but are aggressive towards their own kind not towards others though, when the pairing does not work or one is left out of pairing they will flare their fins before attacking, but since there is nowhere to run they are forced to fight. This is why they are usually best kept in a bonded pair or solo.
Tankmates:
Banggai Cardinalfish is good with a lot of fish but of course, there are some fish that will not take them. Some fish that are not suggested with them are Anglers, Eels (Rounded Toothed Eels are ok), Groupers (Marine Betta are fine), Lionfish / Scorpions, Seahorses / Pipefish, Sharks and Rays, and most Triggerfish. Mostly not anything that it will out-compete for food or big enough to eat them.
Feeding:
They could be fed feeder shrimp, Pellets, Brine Shrimp, Copepods, Mysis Shrimp, Flakes, Frozen, Krill, Clam and etc.
They should be fed Live or Frozen to start out if they are not taking the Pellets and Flakes, as you go on they should get used to it and start eating Flakes and Pellets. These are more Crepuscular so feeding near that time would be best but anytime would work Dusk working the best.
Breeding:
They should be easy to breed, the female should go up to the male making a trembling like movement. The male should tilt and this is repeated until the male swims away or opens its mouth. If the male does open its mouth the female will lay eggs for the male to pick up in its mouth, they should produce up to 90+. These are mouthbrooders so when it opens its mouth you can see all the eggs/fry this should last maybe a month. After they are released and should be fed brine shrimp and other things. Also, removing the male is best and after he spits them out you can put him back.
