i would still need to do pwc right?
Yes. larger than normal. Poly filters or prime etc will also help.
also, i guess with your initial reaction with having both fish on my qt is not a good idea?
With just one fish NH3
can get bad quick. It is possible with both but it will take 2-3 WC
a day and lots of monitoring. The NH3
alert badges are a good idea. also by having both in QT together both will have to be treated. Not the best plan but depending on your situation you may not have other options.
