to setup this QT it requires to be fully cycled aswell correct? and does it require a light? ive also ready online the paracite cant survive past 2 weeks specially if its the temp is 78+ to speed the life cycle no?
Doesn't have to be cycled. You can manage ammonia with water changes, or prime (can't mix prime and copper though), or tank transfers.
Does not require a light.
2 weeks is probably somewhere in the normal range for ich to complete its life cycle. It can take as long as 76 days, however. The feeding stage lasts about 3-7 days.
