So I noticed 2 dead fish in my 20gal nano on Friday. Have 2 clownfish and a blue chromis still alive in my tank, I noticed marine velvet covering the two clowns. I went out and bought “Kick Ich & Rally.” I posted this on this forum and people said I need to quarantine. Today I put all 3 in a 5 gallon tank with copper, filling it with the medicated water from my 20 gallon (worried about mixing the medication?) I have in the 5 gallon an aerator, heater, temp gauge, and the 3 fish. Need opinions on where to go from here?! Thanks I’ll attach some pictures!
