firefish fin

[buddah]

i have had my 2 firefish in the display tank for about 4 days and they are very energetic and know their territory. but one has a small split in his tail. is this something to worry about or is it just something that happens?
thanks in advance

Don't worry about his fin, it will grow back in a few days. Its quite normal for fish to get their fins ripped every now and then.
