I did a search to see if anyone had asked about this before, but I couldn't find anything specifically.
I'm starting up my first "real" tank. I grew up with someone who knew nothing about the hobby but loved fish... yeah. I did some research as a teenager and knew she was doing things wrong, but she wouldn't listen to me, so.
ANYWAY. Now I've inherited the tank and want to do things right. It's a 20 gallon high, and I'm about to start my fish-free cycling. While I'm doing that, I also want to get started getting the equipment I'll need once I do have fish!
My goal, once the tank is cycled, is to have this livestock setup:
However, I do plan on adding just one group of livestock at a time, as I'm most likely going to have to get them from different shops.
Soooo, that says to me that I should quarantine before adding, at least after the first group (the neons) is in.
I'm wondering if I can run a 5 gallon quarantine tank for these guys. I wouldn't ever have more than 6 in the 5g tank at a time, and while I know that would be too small for even that few in the long-term, would it work for a quarantine set-up? I don't have a lot of space and I really don't want to jump to a 10g just for my quarantine rig. I don't plan on having it run constantly; I'll just have its filter connected to the main tank so I can switch it to the quarantine tank when it's needed. Obviously if I moved to bigger fish or a bigger set-up, I wouldn't be able to use the 5g as a quarantine any more.
Honestly, I'd really prefer a 2.5-3g quarantine tank, but from what I'm hearing, even a 5g would be really pushing it.
SO. Opinions? What sort of quarantine set-up should I have for my 20g mostly-tetra tank? Thanks in advance!
