I've got a fantail goldfish 2 weeks ago as a gift from someone. Poor dude was in a fishbowl. I felt so sorry for it, I brought it a 10 gallon tank thinking it was enough. I found out about the nitrogen cycle and how he needs to be in a 30 gallon tank at the very least about 2 days after he was in the tank. He's been in the tank for around a week and a half now and I've been testing water parameters and doing daily 10-20% water changes. So far, pH is 7.5, ammonia is 0.25/ nitrites is 0/ nitrates is 0. I'm not even sure if the cycle has started :/ Water temperature is around 16 celcius (60 Fahrenheit ). Anyway, I've been desperately searching for an affordable 50 gallon tank and I've finally got one today (I'm still a student after all. Spending all my part time job money to take care of my lil one ). I was wondering if I should leave my fish in the 10 gallon tank while doing a fishless cycle with my 50 gallon? Or should I just put my fish in the 50 gallon straight away and do a fish-in cycle asap, since the 10 gallon should be in the process of cycling as well?
