Fin loss is usually easy to avoid and easy to fix. It can be avoided by checking all tank décor before adding it to the aquarium. Because betta fins are so fragile, they easily snag on plastic plants or sharp rocks or driftwood. An easy test can be done to avoid sharp objects. Simply run a pair of women’s pantyhose or nylons over the tank décor. If the nylons don’t snag or rip, they will be suitable for a betta tank. In many cases, the object can be filed down or sharp parts can be removed. Often plastic plants will cause fin loss so you may find better luck with silk or most live plants instead.
Of course, it’s best to not add fin-nipping fish to your tank. Bettas become easy pray for quicker swimming and aggressive fish. Barbs and most tetras should be avoided in your betta tank. If you notice a fish nipping your betta you should remove the fish or the bettas as soon as possible because nipped fins can become infected and treatment could become more complicated.
Betta fin tissue can heal quickly and most mild to moderate spits or holes can heal themselves without use of any medications or tank additives. It is prudent to keep your tank water clean when these minor injuries occur so as not to allow infections to develop.
