Hi, I have a WC L200 HF that has a very concave stomach. I also have a L128 that is fine. Both are currently in my main tank 125g bc my cycle had crashed while using PraziPro. Should I move him back to the 10g QT tank now thats it’s back stable or treat my main tank with Prazipro? I did see him poop a little dark yesterday.. I know they Can be hard to acclimate. Any help would be greatly appreciated..
