I've had these 2 ladder loaches for about 5 months and they've been fine. They are now really twitchy and never stop.
They're always breathing hard/fast and are either swimming around the tank really fast and twitching or hiding.

Tank: 75 gallon
WC: 30-40% Every week
Ammonia: 0
Nitrate: 0
pH: 7

Every other fish is fine but these guys are acting weird.
Any suggestions?
