How to Select Fish For Your New Freshwater Aquarium
By Jason MacParland
New freshwater aquariums owners often can’t wait to add a lot of colorful fish to their established tank. While it is tempting to add the best looking fish to the first aquarium it is beneficial to select compatible fish so that the chosen fish live happily. This article will provide information on how to select fish for your new aquarium.
Requirements of Various Fish
Barbs are tetras are small colorful fish that look very beautiful. The tetras available in local fish shops are usually less than 1.5 inches while the barbs available in local fish shops are usually less than 2.5 inches. Barbs make great additions to a community tank but some barbs like tiger barbs are known to nip fins so they should be kept in a species only tank. Tetras on the other hand do well in small schools since they feel comfortable when they are with others of their own species. Small loaches and cory cat fish can be kept with barbs and tetras.
Livebearers like guppies and swordtails can be kept in community tanks since they are peaceful. Since mollies require brackish water to grow well it is recommended not to keep mollies with freshwater fish.
Goldfish are cold water fish that should not be mixed with tropical water fish since their temperature requirements are different.
Bettas a very beautiful and common fish are very territorial fish and males should be kept alone. Female bettas can be kept in groups of five or more provided there is enough place to hide.
Cichlids are aggressive fish that need to be kept with compatible tank mates. Oscars are large cichlids that should be kept alone. Cory cat and clown loaches fish do well in small schools.
Things to Keep in Mind
While learning how to select fish for your new aquarium you should remember that your aquarium should not be over crowded. Fish in overcrowded aquariums are prone to illnesses due to stress and bad water conditions. The fish you choose should also be comfortable in the aquarium you have. Small fish like neons and barbs can be kept in aquariums more than 10 gallons but Oscars or other larger fish need bigger aquariums. Plecos that are commonly sold as sucker catfish grow to a length of 24 inches and they should not be kept in tanks that are lesser than 60 gallons.
While selecting fish for your new aquarium you should stock your tank based on the adult size of the fish. Oscars are large fish that reach a size of 12 inches and Australian arowanas can reach a size of 26 inches. The inch per gallon rule is not the right way to calculate the number of fish you can keep since this rule is only meant for slim bodied fish like tetras. As a general rule you should give 20 gallons of water per goldfish, 55 gallons of water per Oscar, 2 gallons of water per tetra or barb and 5 gallons of water per betta. Small sized loaches and cory cat fish should be given 5 gallons of water per fish. Since clown loaches can grow to a size of 18 inches and they need to be kept in small schools these fish should be kept only in large tanks.
