Hi, so I'm putting my boys in a divided 5 gal tank once I'm back in college land... I suddenly got really worried that Fishstick and Button might get sick from each other . Is that likely? (I've only had Button for about a week and he's been in QT and seems perfectly healthy). Should I take any precautions when putting them together or just have meds on hand for more common things like Ich and Fin Rot? I've been switching about 8-16 oz of the water from one's tank to the other for the past few days in order to acclimate them to one another's bacteria... anything else I should do? I seriously would be devastated if one of my little guys got sick and died... they're kinda like my children...
