I've got a similar setup, 75 gallon with a canister filter. Placed one heater near the intake and the other by the output. Temp stays steady at 84°F. How often you doing water changes?

Before jumping to equipment, try a round of salt. A tablespoon per 5 gallons can help with mild fin issues. Just don't use it long-term with Rams—they're sensitive to salt.

Agree with Limey on the bacterial angle. If it's fin rot, you'll see progressive deterioration. If it's static or improving with cleaner water, it's likely physical damage. Monitor for a few days before jumping to meds.
