welcome to fishlore!!! im sorry for the ich on your fish
rams are super sensitive and dont handle meds well...even if they are organic ...did it change color after adding the meds or before? do you know the readings for
ammonia, nitrites, and nitrates on your tank?
as new as the tank is, and with the additives you have been adding (stress zyme, stability) and the added ich attach, it could be from a combo of all and an uncycled tank ....
I would try the warmer temps for 2 weeks minimum, daily water changes of 30% with 2 gravel vacs a week (for the ich spores) and find some prime or ammo lock to add with your daily water changes....I would stop using stress zyme and stability as they are not self sustaining bacteria and do more harm than good on your cycle process....of course unless you plan on using it weekly for the life of the tank......
each fish is effected differently and hopefully nothing changes with the others!! good luck!
