I was feeding my fry and I noticed this one slightly derpy fry spastically swimming around. is there anything I can do for this little fella (these are mollie fry) would salt help? It's like he swims in short spastic bursts and when he stops he slowly sinks. The tank I keep them in is the 5.5 gallon from petsmart and it's only half full so around 2-2.7 gallons right now. I kind of want this little guy to survive because he looks like he has a little sail fin in him whereas all the other are short fin dalmatian fry.
Ammonia: >.25 (water change today)
Daily to every other day water changes.
And the fry are only about a week old.
Any advice is appreciated, Thanks.
