According to juvenile blue tangs are bright yellow with blue spots by their eyes, and their fins have light blue tips. They do not have fully blue bodies until they are fully matured. They are native to the Pacific Ocean but can also be found in some parts of the Indian Ocean. You will want to have coral in your tank with these as they eat the excess algae that grows on it.

Bicolor Dottyback

This pink and yellow fish is a real beauty. Don't you just love how the colors seem to divide its body perfectly? This fish is great for beginners as they are pretty low maintenance. Your tank should be at least 30 gallons and have a ton of live rock so they have plenty of hiding spaces. You should talk to the fish store staff before choosing tank mates for these fish as they can get very aggressive and should not be put with certain other fish because of that. They do not even do well with others of its kind.

Helfrichi Firefish

These gorgeous fish will make your aquarium just that much better. Just be sure that you do not put more than one in your tank or they will fight unless they are a bonded pair. They do well with other fish but are also territorial, so they can be a bit territorial. They need at least a ten-gallon tank or larger to spread their fins. They enjoy loose coral rubble as part of the decor. Also, be sure they have a tight fitting lid on their tank because they are jumpers.


Scorpionfish can be amazingly beautiful or super ugly depending on the kind you get. One thing you will need to be prepared for if you get one of these is to have a really big tank. They require at least a 50-gallon tank to survive. While they are not a real big fish, the reason for the larger tank is so that they have space to not injure other fish with their venomous spines. Don't let that worry you though. They are a very popular fish because of their hardiness. They do really well in an aquarium and are resistant to most fish illnesses. But, they are also predators, so their tankmates should be larger than they are.
