Is something wrong?
I have a 30 gallon tank with 6 fish in it, 3 serpae tetra and 3 zebra danio. The three zebras seem to be fine, but as of recently my 3 serpae have begun losing parts of their top fin. The tips of their bottom fins also look white. Their tail fins seem to be fine though. Any ideas as to what this is? I've had them for about a month so far and they've shown nothing else wrong.
They are all eating normally, and their tank is currently cycling so their nitrite just began to go up to .25 and their ammonia is about .75.
