To create a perfect biotope for this fish, you may need to give it a lot of grazing room as well as several spots to hide in. It may take in miniatures as hiding places, but crevices in rocks are much more suitable for it resembles more of its natural habitat. It is about 2-3 inches in length, and prefers high lighting conditions. Your tank should be kept about 75-78 F with a pH of 8.1-8.4 (alkaline). It loves to swim so your tank should have a minimum size of 30 gallons. Corrals and plants can also be added in your biotope to provide places for your fish to lay its eggs along with your rock formation.
The Bicolor Pseudochromis has a semi-aggressive temperament, and can be highly territorial. It will not tolerate meek, mild-mannered, slow-moving fish in the tank. It's a bottom-dweller, and targets most of the shrimp in your tank (anemone shrimp. If you love your shrimp, you may want to reconsider if you are considering on adding this in your tank.
The color of your Bicolor Pseudochromis will fade in captivity because of lack of food variety. Give them a selection of food to promote their colors such as mysis shrimp, enriched brine shrimp, seafood, or other frozen preparations designed to care for marine fish. This fish is sold for as low as $12-$13 per fish. It is advised that the fish be quarantined for 2 weeks before being added to the tank.
Blue-Green Chromis:
This is one of the hardiest and easiest fish to take care of in a salt-water aquarium. This fish is also known as Blue Green Damselfish or Green Puller. The color is somewhat between green and blue, depending on lighting conditions. However, a male will change its color to yellow when it's in a nesting mood. It is a great addition in your tank because of its peaceful nature and for its unique color. It's quite different to see this fish live compared to pictures.
When you buy Blue-Green Chromis, it is best to buy them in odd numbers rather than one by one. For small gallon tanks (around 20-30) 3 would be an ideal number. This fish is highly dominant, and introducing fish one by one would only resort to battle for dominancy in the tank. Blue-Green Chromis do not take that long to bond together to form a school. It does, however, have a dominant member once the school has been formed. Smaller, weaker members are often It does not require much set up in the tank, making it perfect for those who are just starting on the hobby. If you have created a perfect biotope for this fish, you may be lucky enough to see them spawn. The male will prepare a nest in the sand, in which several female of the species will share. Once fertilized, the male will guard the nest until the eggs hatch and encourage water flow by fanning the nest. Any eggs that are not fertilized or showing no signs of hatching will be eaten by the male.
Blue-Green Chromis will have to be fed with a variety of food to keep its color. Mysis shrimp, frozen preparations, and enriched brine shrimp can do just the thing. You can buy Blue-Green Chromis for as low as $5 per fish. Quarantine your fish for 2-3 weeks in before you put them in your tank to make sure that they don't have any disease that can infect other tank inhabitants.
