The elephantnose fish is a carnivore and will accept all types of meaty foods. Only one elephantnose or more than five should be kept per tank because aggression can build up if two to four are together. The probe in front of the fish is a sensitive electrical organ that it uses to find food. An elephantnose does best with a home which can be a cave or cave like structure. |- |[[Peters' elephantnose]] || ''[[Gnathonemus petersii]]'' || || 9"+ || || || |- | colspan="7" style="background:silver" |[[Pantodontidae|Butterflyfish]] |- |[[Freshwater butterflyfish]] || ''[[Pantodon buchholzi]]'' || [[Image:Pantodon buchholzi.jpg|50px]] || || || || not related to saltwater butterflyfish |- |} ==[[Siluriformes|Catfish]]== {|class="wikitable" |- !

Males may claim small territories and occasionally minor battles may occur. The Phantom tetra goes well with other tetras of similar size. They also prefer floating plants. |- |[[Black neon tetra]] || ''[[Hyphessobrycon herbertaxelrodi]]'' || [[Image:Black neon tetra.jpg|50px]] || 1.6" (4cm) || Community || Intermediate || this fish is similar to the neon tetra other than coloration. |- |[[Black tetra]] || ''[[Gymnocorymbus ternetzi]]'' || [[Image:BlackTetras.JPG|50px]] || 2" (5cm) || Community || Easy || a highly spirted fish that may occasionally chase its own species as well as harass slow moving fish with long fins. This fish is very hardy and can stand a variety of water qualities. Disease is not a big problem with the black tetra. The black tetra is also known as the black skirt tetra. The female black tetra is more robust and larger than the male. |- |[[Bleeding heart tetra]] || ''[[Hyphessobrycon erythrostigma]]'' || [[Image:Kirschflecksalmler-W.jpg|50px]] || 2.5" (6.5 cm) || Community || Intermediate || the bleeding heart tetra is distinguished by the small red spot on both sides of the fish. This fish is very prone to diseases, and can grow larger than most tetra species. It is not recommended for beginners. |- |[[Bloodfin tetra]] || ''[[Aphyocharax anisitsi]]'' || [[Image:Bloodfin dec20 2006.jpg|50px]] || 2" (5cm) || Community || || |- |[[Bucktooth tetra]] || ''[[Exodon paradoxus]]'' || [[Image:Bucktoothed Tetra Image 001.jpg|50px]] || 2" (5cm) || || || will eat smaller fish and harass larger fish |- |[[Buenos Aires tetra]] || ''[[Hyphessobrycon anisitsi]]'' || || 3" (7.5cm) || || Easy || |- |[[Cardinal tetra]] || ''[[Paracheirodon axelrodi]]'' || [[Image:Paracheirodon cardinalis.JPG|50px]] || 2" (5cm) || Community || || |- |[[Cave tetra]], [[blind tetra]] || ''[[Astyanax mexicanus]]'' || [[Image:Astyanax mexicanus.jpg|50px]] || 4.7" (12cm) || || Easy || cave tetra is the blind cave form of the Mexican tetra. The blind cave tetra is easy to care for and is hardy. The fish is born with eyes, but they quickly deteriorate leaving behind two scars where the eyes once were. The blind tetra needs to be in a shoal in order to show peaceful behavior, and to prevent fin nipping. Despite their lack of eyes, the blind cave tetra can easily avoid other fish and obstacles in the tank. This tetra prefers low to moderate lighting. |- |[[Congo tetra]], [[Lufundi (native name)]] || ''[[Phenacogrammus interruptus]]'' || [[Image:Phenacogrammus interruptus (aka).jpg|50px]] || 3" (7.5cm) || Community || Intermediate || Sufficiently peaceful for home aquariums, though it may bite fishes smaller than its size. It is more comfortable in indirect light. Over-head lighting is preferred and under no circumstances should light be directed at the front or rear glass. |- |[[Emperor tetra]] || ''[[Nematobrycon palmeri]]'' || [[Image:Kaisertetra.jpg|50px]] || 2" (5cm) || || Easy || |- |[[Garnet tetra]], [[pretty tetra]] || ''[[Hemigrammus pulcher]]'' || <!-- Missing image removed: [[Image:Hemigrammus pulcher.jpg|50px]] -->|| 2.5" (6.5cm) || Community || || |- |[[Glowlight tetra]] || ''[[Hemigrammus erythrozonus]]'' || [[Image:Redglow.jpg|50px]] || 1.5" (3.75cm) || Community || Intermediate || |- |[[Green neon tetra]] || ''[[Paracheirodon simulans]]'' || [[Image:Paracheirodon simulans.jpg|50px]] || 1" (2.5cm) || Community || Intermediate || |- |[[Lemon tetra]] || ''[[Hyphessobrycon pulchripinnis]]'' || [[Image:Hyphessobrycon pulchripinnis.jpg|50px]] || 2" (5cm) || || || |- |[[Neon tetra]] || ''[[Paracheirodon innesi]]'' || [[Image:Neonka obecna paracheirodon innesi.jpg|50px]] || 1.6" (3.75cm) || Community || Intermediate || the neon tetra is sensitive towards water quality and is susceptible to many freshwater diseases. However, the fish is very peaceful and will not attack another member of the tank. Females are larger than the males. Due to their small size, the neon tetra should not be kept with large fish. Neon tetras are also very delicate and any harassment they may receive can result in death. This can be prevented by putting them with other small community fish or fish known to ignore their tankmates. The neon tetra feels the most comfortable when in groups. |- |[[Penguin tetra]], [[blackline penguinfish]]|| ''[[Thayeria boehlkei]]'' || || 2.5" (6.5cm) || || || |- |[[Rummy-nose tetra]] || ''[[Hemigrammus rhodostomus]]'' || [[Image:Brilliant rummy nose.jpg|50px]] || 2" (5cm) || Community || Intermediate || |- |[[Serpae tetra]] || ''[[Hyphessobrycon serpae]]'' || [[Image:Serpae tetra.JPG|50px]] || 1.75" (4.5cm) || Community || Easy || this fish may nip the fins of slow moving fish or fish smaller than it.

However, care should be taken if interacting physically with the pacu as their powerful jaws can crush human bone. The Pacu is a peaceful fish that requires at least a 200 gallon tank when fully mature. It is omnivorous and can be put with large cichlids, but avoid smaller fish. Despite their similar appearance to piranhas, the pacu is not suited to eat meat very well, as their natural diet of nuts suggests. Be aware that this fish can grow to four feet and the owner must be prepared to house them in a very large tank if they wish to keep the fish (200 gal minimum). Also be aware that this fish grows very fast, and can grow as much as one foot in the first year. |} ==[[Cichlidae|Cichlids]]== {|class="wikitable" |- ! Common name !! Taxonomy !! Picture !! Size !!

In the U.S., the fish is often called "[[betta]]", although this word is actually the name of the [[genus]] that includes more than 60 [[species]] other than the [[Siamese fighting fish]]. Multiple males in a tank will result in conflicts and possibly death. Females can be housed together in groups of 4+ in a tank, though they may become territorial and attack each other. Males have long flowing fins with vibrant colors, and females have shorter fins. This fish is best put with fish that do not nip fins, as the fins of the betta are easy to attack. They should also not be housed with other fish with long, flowing fins as the Betta may confuse it with another, and attack. |- |} ==[[Live-bearing aquarium fish|Live-bearers]]== {|class="wikitable" |- !

At youth, the shark has a high dorsal fin, a plump body, and radiant colors. However, as the fish matures, the characteristics of the fish changes drastically. The dorsal fin becomes shorter, the fish achieves a more cylindrical shape, and the color fades to a dark brown. The fish is not suitable for fish tanks because of the size it can grow to. The highfin cannot be housed with tropical fish due to their lower temperature preferences. The highfin prefers to be in a school, so more than one should be housed together. The "shark" is a peaceful fish, and will not openly attack others. Highfins are bottom dwellers and omnivorous. They will eat invertebrates and scrape algae off rocks. |- |Chinese hillstream loach|| [[Beaufortia kweichowensis]] || [[Image:Beaufortia kweichowensis.jpg|50px]] || || || || |- |} ==[[Gymnotiform|Neotropical electric fish]]== {|class="wikitable" |- !
