One out of my two datnoids (both about ~6-7 inches long) have been scratching it's gills, chin on the bottom of the tank, flashing, and twitching. I've checked my water parameters and there are no ammonia, no nitrite and nitrates are 20-30 PPM. (this is a newly cycled tank) I did a 40% water change earlier today, normally do 40-50% every 3-4 days, dosed, prime before adding water, added aquarium salt to the tank (.1% based on 100 gallons). There are no visible signs of any type of ich, redness on gills, etc. I've NEVER fed any type of feeder fish, they are on shrimp, tilapia, and freeze dried krill and I'm uncertain if this is normal behavior for tigers or this could be some type of external parasite.
