I have a newly acquired vlamingi tang presenting with a skin lesion dating back to 3/29/2023.
History
Purchased on 5-6" 3/24/2023 with 20 other specimens from a local aquarist braking down their system.
Specimen in question did not initially present with any visible abnormalities and accepted food the second day.
Acclimated to a quarantine holding system approximately 175 gallons in volume.
Quarantine system was fallow for 130+ days and remained cycled by regular additions of ammonia chloride, initial bacteria culture was added from display tank.
On 3/24/2023 as seen in the graph, I experienced a small ammonia spike in the system, addition of amquel (25ml) and turbostart 900 by fritz (100ml) was added to manage.
On 3/28/2023 another specimen Paracanthurus hepatus from the same lot of fish, presented with cryptocaryon irritans.
On 3/29/2023 preformed 150 gallon water change to remove amquel. pH fluctuation from 7.95 to 8.1 during water change.
On 3/29/2023 commenced with copper safe treatment. (See graph)
On 3/29/2023 at ~ 8:00pm the specimen in question presented with a small 1cm x 1.5cm red and white lesion on the lower abdominal area. Pictures with red arrow, appears to be improving. Pictures of lesion taken today 4/1/2023, no pictures available from 3/29/2023.
On 3/31/2023 at 12:00am to 4:00am I preformed a medicated bath in KanaPlex (kanamycin) (3.5 gallons, 1.5 scoops roughly 2x the normal dosage). Air-stone added and temperature controlled by holding container in tank.
On 3/31/2023 at 8:00am noticed white lesions on opposite side of fish developed. Respiration rate had increased significantly.
On 3/31/2023 specimen accepted food normally.
On 4/1/2023 at 12:00am to 4:00am I preformed a medicated bath in KanaPlex (kanamycin) (3.5 gallons, 1.5 scoops roughly 2x the normal dosage). Air-stone added and temperature controlled by holding container in tank.
On 4/1/2023 at 8:00am noticed white lesions on opposite side of fish have roughly doubled in size.
On 4/1/2023 at 11:00am preformed skin scrape and wet mount slide. No signs of uronema.
My first thought is acute toxicity from possible over dosage of KanaPlex. Perhaps, I should have used my mg scale.
Looking for feedback on best course of action.
