svelez Posted September 4, 2022 Share Posted September 4, 2022 I am wondering if anyone has any experience performing water changes and feeding fish during the week long quarantine med trio. Here is why I ask: Two weeks ago, I had a shipment of wild caught rosy loaches arrive. Besides two that sadly didn't make it during shipping, the rest all looked healthy and very active. Total of 21 fish. They were very thin, which I was expecting, but at least I had no problems getting them to eat. I have had them in a 20 gal. long quarantine for two weeks (and have every intention of keeping them in there for several more!). I've been using a sponge filter that was in my display tank and fully cycled, although I did daily water changes for the first two weeks to make sure the filter could keep up with the new bio load. I also had included a bit of poly bio filter to help keep an eye on water quality. I was feeding twice a day, as I saw elsewhere online (seriouslyfish.com I think) that this might help the new fish gain weight. It seemed to work! With the exception of a few smaller ones who are still thin but otherwise act okay, the rest have fattened up very well, maybe even too much. I admittedly struggle to find a balance between making sure the younger ones are getting enough to eat, but not overfeeding 😞 Anyways, all seemed fine until today, when I went to do a water change and discovered one of the larger males dead. I did not see any visible sign of illness, although it almost looked like there were some spots of blood internally. Hard to tell whether that was internal bleeding or just because these fish are so tiny and practically see-through. There were two lesions on the side of the dead fish, but I don't know if that could have been from the other fish picking at him after he died. They eat anything unfortunately. I am pretty sure I would have noticed open sores on a fish if he had them earlier, but again, not positive. After removing the dead fish, I did a 50% water change, refilled and dosed with the med trio. I was eventually planning on using the med trio, given that these are wild caught fish, but was trying to hold off until all fish had gained decent weight. I know parasites could of course prevent that, but I never saw any signs of white stringy poo. My only concern now - apart from the fact that I don't know what killed the fish - is not feeding or cleaning the quarantine tank for a whole week. Does anyone have any thoughts or recommendations? Thank you so much in advance, and if I did not provide some critical piece of info, please let me know. Link to comment Share on other sites More sharing options...
