We know what you’re thinking, but don’t let the name fool you. With patterns and colors galore across its 700 species, even the most pedantic of aquarists won’t have trouble finding a killifish to match the color scheme of their tank. Speaking of mating, the killifish is one of the easiest aquarium fish to breed and requires far less specific conditions than some other species of fish.Īside from its resilience and the ease with which it can be bred, the great allure of the killifish is its colorfulness. With little goal beyond enjoying its own existence, the killifish is unlikely to start any battles with other fish in your aquarium, so you can be certain of a peaceful tank as long as you keep just one male killifish (they can get quite aggressive when mating season rolls around). Go with traditional flakes instead and your Cory catfish will likely grow weak, losing each meal to faster and more active fish. Though quite a sociable bunch, Cory catfish are calm and non-confrontational, which makes them the ideal freshwater community fish.Ĭory catfish are primarily bottom feeders and so should be fed using sinking pellets.

If you’re hoping to build a community aquarium as opposed to simply housing a single species in your tank, you should consider purchasing a Cory catfish or two. If you are happy to proceed, it is recommended that you keep guppies in sets of threes, with one gallon of water per fish. It is important to note that guppies, unlike goldfish, are sociable creatures and so should be kept in groups, which may be a problem if you would like to avoid the stress of caring for multiple fish. Their popularity can also be traced back to their vibrant colors and hypnotic tails, which are most commonly seen in males. Guppyīecause of how easy they are to care for, guppies are almost as popular among novice fishkeepers as goldfish. If housed in an adequately sized tank – a 20-gallon model is generally suggested – you can expect your goldfish to grow up to 14 inches in length and live for upwards of a decade (the oldest recorded goldfish made it to a staggering 43 years).Īvailable for only a couple of dollars from most pet stores, goldfish should be high on your list if you’re hoping to stock your tank on a budget.
