Betta Plant Selection

Betta plant selection doesn't usually take too much of an aquarist's time. They see a plant they like, they buy it, get it home and place it in their Betta tank. Done, right? Nope.

1 - Plastic or Natural

We first need to look at the two types of Betta plant construction. There are benefits and negatives to the addition of both plastic and natural plants to your Betta tank. Plastic plants do not die, nor do they dirty up your water. The downside is, they do not create oxygen for your Betta tank. Natural plants do create much needed oxygen, but can make your water harder to clean. Natural plants also die, and need to be replaced. The choice here is up to you.

2 - Betta Plant - some common natural types

There is no limit to the number of plastic plant colors, sizes and shapes you can get for your Betta tank. But the number of plants that are healthy and not dangerous to your fish, and actually perform a needed function are limited. Water lilies and other Betta plants that float are instrumental in providing cover for your fish, and also in giving your male a place to create his bubble nest. Another great Betta plant is the water wisteria, with round leaves. Bettas have been known to "sit" on the wisteria's underwater leaves, like a butterfly. Also consider plants that have a large part of their foliage underwater. Bettas like to "hide" from time to time, and a Betta plant like the Java Fern and Photos plant are excellent.

3 - Betta Mating Tank

A consideration should also be made as to what type of plant to provide in your Betta mating tank, should you decide to breed them. The female Betta will need a place to hide from the male, and if you place a long trunked plant near the filter, the two will provide her a nice escape. A Chinese evergreen or philodendron make good choices here. Plants in your Betta mating tank also make for a more natural breeding ground.

Betta plants add ambiance, visual pleasure, and oxygen to a betta tank. They also provide protection and a place to build a bubble nest. If you need more information about betta fish, check out the betta blog at www.BettaFacts.info.
