ADVICE NEEDED
I cannot work out what is happening.
All parameters fine.
Had a pleco that showed same symptoms and died a few months ago.
Our new brislenose is now displaying the same freyed dorsal fin. Active atm but last one went downhill very quickly.
Our other small juvenile plec is fine , all other fish in tank fine.
What could this be / what can we do?
