The Bala Shark, scientific name Balantiocheilos Melanopterus, isn't really an actual shark but was named as such because of its appearance, which features silver coloring and tall dorsal fins. They make an excellent addition to an aquarium due in part to their mild-temperament as well as their beauty and grace. These energetic fish also form gorgeous schools and are compatible with several different tank mates to add an interesting variety to your aquarium.
Betta is a popular tank fish and its maintenance is least painful. However, it does need care and you must be observant about its heath. A sick Betta is easy to spot since naturally the fish is very active and vibrant. If you have had the fish for a while you will be able to spot immediately when they are unwell.
I still remember the first time I saw two beautiful looking fish in a friend's house. One fish was blue and the other was red, and they were swimming majestically in their fishbowls. That was my first encounter with a fish species known as Betta fish or Betta Splendens or Siamese Fighting Fish (three names that refer to one fish).
