I am a fairly new aquarium owner tho i had them as a kid this is my first experience with owning my own. I started with two sword tails two guppies and two albino catfish. now a year later i bought a redtipped shark wich i was told would do well in my tank. A week later i noticed that my male sowrd tail has a gap or split in his tail by his sword. Is this a big problem? Was it the shark? they all get along fine and appear healthy.
