Unfortunately I've had an ich outbreak in my 400 gal after some new arrivals. So started a treatment of formalin/malachite green mix and am getting positive results, been dosing 1oz per day with about 30% water change daily. Did not raise temp till today, going to 86 degrees but my catfish is acting off, listless and listing odd directions. I was under the impression that formalin/ malachite was safe for scaleless fish? Could this be the issue?
Achara cat acting weird

I’d suggest reducing the temps if ur dosing meds.
Malachite green has been mentioned to bother sensitive fish. Can try half the dose.
I've had it at 79 since Monday but I've read to accelerate the life cycle temp should be taken to 86 to compliment effectiveness of meds.
It does. It also reduces the o2 content in the water. Ur fish maybe experiencing that. So better to just reduce any risk of problems.
Ok so raise temp= lower oxygen = shorter med time but equals stress and problems.
Lower temp= longer med time for possible sensitive fish = stress and more problems.
All this equals quarenteen tank for best outcome? Haha! No options..........just gonna hafta wing it I guess.
I always increase surface agitation or add air stones when cranking the heat way up to mitigate the o2 problem.
Temp doesn't have to be 86F to increase lifecycle of ich. A temperature of 75-79F is sufficient to increase the lifecycle for medication use per
CIR920/FA006: Ichthyophthirius multifiliis (White Spot) Infections in Fish
Ichthyophthirius multifiliis (Ich) is a protozoan parasite that can cause severe losses in aquaculture and aquariums. It is introduced via new fish, substrates, plants, or equipment. Preventive measures include quarantining and treating new fish, holding plants without fish, and disinfecting...
If you want ich to stop reproducing, temperature should be around 87F (although some ich are showing resistance). To kill most ich, temperature must be 90F+.
All is good with Achara, went out and bought an isolation tank set up. I think he was medication sick but is 100% now. I lost four pike cichlids to the icy even after medicating, temp increase, water changes like a mad man. Funny thing is I had other cichlids in the same tank that did not show one sign of ich and are completely fine.
