But you are correct my question is the housing of both species together, was thinking it might possibly work seeing as my goldfish are over 3 years old and I've only had them for about 5 months there previous owner was an old lady she kept them at room temperature since they were fry which her temp was 80° which is super high for goldfish I know but i tried putting them in colder water around 68 to 70 " i did the whole current water temp in bag and float 35 minutes" and all they did was sit sideways on the bottom, I put them back in there original temp of 80 and they start swimming around normallyI'm starting to see there was a misunderstanding on both sides, please forgive my rudeness
