Hi. I have Malawi peacock/haps 75g. I just noticed a couple days ago one not eating so I've been keeping a close eye on him when i would feed and looking out for stringy white pooh.It has been confirmed he's not eating and i noticed stringy feces. Immediately I stopped feeding, tested water with api master test kit. 0-0-10-8.0ph-78F. Water parameters good. Right now I'm preparing treatment epsom@2tbs/10gal.... i have metro on hand- question is should i use the metro with the epsom ? And just recently i moved 3 syno-petricolas from the 75g to a 45gal 2 days before i noticed the one not eating. Should i treat that tank too with any meds or epsom as a precaution ? In the 45g i have about 10 juvies and the 3 syno cats. Thanks for your time and for any input.
