Heavy sigh. You know the stages of grief - denial, anger, sadness, and finally acceptance. I don't even have the energy to cuss. I'm going to fallow my tank or I will never get to get a new fish again - no to mention keep the ones I have happy.
For the start, I'll try to get my two sickies out and into a copper bath. Fishy Biz had malachite green. I will leave them in the hospital tank while I'm out of town. When I get back - as timing permits - my clown will go into the nano. (No fish in there for months.) Then I will cycle my other fish through the hospital with the smaller ones headed for the nano and my larger ones will stay in the hospital (exchanging the 20 for a 29g) for the duration.
How long does it take to seed a sponge? My nano is clean. Can I just put a sponge in there and let it sit for a few days? Maybe a stupid question - can it be a new, clean kitchen sponge or should it be a filter-type sponge?
BTW - thanks everyone for holding my hand.
