On this thread we will discuss about the general brackish water fish that would look absolutely wonderful in a reef. Some of these include guppies, mollies, sword tails, some species of danios, some species of kilifish, mono fish, green spotted puffer, figure 8 puffer, scatts, dragon goby...
Guppies in a reef tank? Yes pleas. Guppies are a very popular freshwater fish but what many people don’t know is that they can be kept in a reef aquarium with proper handling.
