I have a 90 gallon tank in which I have pink tulip eel and a amphivious frog and a few placos The tank is infected with ick and I,m not sure how to treat it. I was going to use quick cure but, everyone tells me different things. First can I use this with an eel and frog? If so, how much of a dosage and for how long? Should I do 25% water changes every day and raise the temp.? I'd hate to lose my eel,I've had him for 4 years. I recently removed a large oscar from the tank because he was terrorizing everyone, I think the stress of him hascaused the ick. Help,how do I handle this situation without loosing my beautiful eel and frog?
