Hello everyone,
Iam hoping I can obtain some help and solid advice. We purchased 7 fish on 3/5/23. I only quarantined them for one week…huge mistake. One of the platys has died - seemingly Dropsy. The second fish is not well. My swordtail has declined. Last Wednesday 3/22/23 I notice one lone white spot on his fin. He was eating and behaving normally. By Saturday 3/25 he had more white areas. I was waiting on Ick-X, paracleanse, and Maracyn to come. The Maracyn I received wasn’t the erythromycin it was Maracyn Oxy. Ive since placed an order for Maracyn antibiotic - waiting for arrival.
Saturday he moved to a 10G QT and I added Paracleanse, Maracyn Oxy and Ick-X.
Sunday I performed about a 25% water change and added another dose of Ich-X
He also has API aquarium salt in the aquarium -2 tablespoons each day x 3 days
My community tank that he was in seems ok except for one of my angelfish as of Sat began to hide and not eat. It is swimming normally when it comes up but seems lethargic. I cant see any fin/skin issues at this point.
I had my water checked at an aquarium store Sunday and my parameters are good.
I use Prime/Stability/purigen
Filter is a Fluval 307 canister and also a Fluval 50 HOB
Temp 80F
Iam scared this is Columnaris and should I treat my entire 55G planted community tank? In that tank we have Mollies, 3 platys, 1 swordtail, 2 Angelfish
Of note, when we went back to the aquarium store the tank that our platys came from was also on quarantine - supposedly for ich.
Here are some pictures of the sick swordtail
