Hello all! I just wanted to get your opinion on something. If you have new fish in QT and those fish get sick BUT you are able to treat it successfully - does QT start all over again once they've recovered? Another 4-8 weeks? I feel like, if my ranchus come through this, QT will be doing more harm than good. I wasn't really prepared for the third ranchu and so I have three of them in a 20 long for QT. They're still small, about 3" with fins, but they are bigger than my other fish and have a lot of body mass. Sayuri is in a separate 10g right now, but they're all so bonded that it's hard to split them up. Sayuri is alone in the 10g right now and she's definitely more skittish/easy to startle while alone. When together, they are ALWAYS together. I don't mind having to do the tons of WCs in the 20g to maintain toxin buildup. I'm just wondering if maybe it's better I just get everyone into the 75g. My other option is to setup the 75g, move over the guys from the 29g, and use the 29g as QT for the ranchus. That way there will be more water volume. So options are.... 1) Get everyone into the 75g ASAP. 2) Continue to maintain QT and tanks as they are for the duration of a new QT period, doing large WCs and buying cycled filters to help with ammonia/nitrite. 3) Move the healthy guys in the 29g into the 75g and use the 29g to re-start the QT period post-illness for the ranchus. Thoughts?
