My Cardinal tetra are not looking so healthy. Can anyone narrow down what they have and advise how best to treat please?
I spotted the first fish with what looked like fungus about 2 weeks ago. I didn't have a quarantine tank available so had to treat in tank. I did two treatments with Seachem Kanaplex 2 days apart, and also added Pimafix and Melafix every day for about a week. Honestly I then took my eye off the tank for a while and yesterday noticed more fish were affected.
I have not seen any dead fish yet and have searched the tank well. The affected fish are eating and behaving normally, no flicking against rocks etc, swimming with the group, no issues swimming. I've just got a quarantine tank setup to move them into to treat (main tank has nerites and a couple of amano shrimp so don't want to medicate that too heavily or often). The affected fish were hard to catch, definitely no issues swimming!
I'm doing a 1 hour dip with Seachem Paraguard before moving them into the hospital tank. Fish don't seem bothered with this.
I have the following med's on hand at home: NeoPlex, MetroPlex, KanaPlex, Melafix & Pimafix, API aquarium salt.
Thinking either daily dosing of Paraguard (as that seems to treat just about everything!) or MetroPlex (on basis that already treated with KanaPlex).
Your thoughts and advice please!!!
