NJ_FishDad Posted September 14, 2022 Share Posted September 14, 2022 Hello. I recently added some additional harlequin rasboras and silver tip tetras to our existing community tank which already had 4 of each. The new fish brought each school up to 7 total. I lost one rasbora a day after intro to what appeared to be pop-eye. A second got cloudy skin and lethargic about a week later and died about 1 day after showing symptoms. The 5 remaining rasboras and 7 silver tips all are acting healthy but two rasboras have fins that are turning white. Photo attached. We're currently treating (2 days in) with the "natural" anti-fungal, anti-bacterial solution. I have ordered the full suite of 3 medications recommended here on AC which will arrive today or tomorrow. So my questions are: What is this? Should I wait for the natural solution to work? Or should I dose with the three recommended medications ASAP to prevent further issues? The tank is fairly new, started 7/23/22. Tank is 38 gallons, no live plants (yet). Tank also contains 2 mystery snails and a single, small pleco. Lesson-learned here as I'm currently setting up a quarantine tank setup for all future additions but I don't want to lose our existing schools. I set this tank up as a project to share with my 5 yo so hoping we don't have a big die off. I've been doing regular water changes and the original school of 4 + 4 rasboras and tetras were really thriving before the new introductions on 9/3/22. Filter is hang on back which I've modified per the guidance on here re: swapping the disposable media with sponge filter material. I'm using the aquarium coop test strips so I'm interpreting my numbers from it as: Nitrate: 0 Nitrite: 0 Hardness GH: 300 Buffer KH: 120 pH: 7.2 Chlorine = 0 And another brand ammonia test strip is showing: 0 Water temp is 76F. Thanks for taking the time to read this. Link to comment Share on other sites More sharing options...
