What fish would you recommend for a beginner who wants an aquarium?

In my opinion, the best fish for beginners is Cory catfish. There are very popular fish in pet stores. Have you had experience with exotic species that died after a few days? A beginner should not have reason to cut his losses since Cory catfish are viable alternatives. They are quite hardy just like their cousins, the African catfish and has armoured box like material running through their bodies. As you can decipher, the fish require very little care and its basically effortless to rear them. This is a convenient choice for beginner hobbyists. These fish have a calm, peaceful predisposition. Some are shy and more timid than others usually those smaller in size. If you are disadvantaged in cash or in kind, one can always take heart in the fact that Cory fish can be reared in covered tanks of any size and dimensions say, 10 gallon aquariums. One needs to be mindful of overstocking just like in other living things. Cory fish are bottom dwellers and its good to keep at least 2 inches of gravel at the tank bottom. Be sure to include rocks and decorations for the fish to explore. As for the water changes, regular and partial changes are recommended. Under the right conditions, these fish have a lifespan of 5 years.
