Hi, as the title says. I got a just stablished tank with two goldfish. They have been really strong and survived the whole cycle process. But now it's time to get more fish, but I dont want to get rid the golds. So my question is: Can I put golds and tropicals in the same tank? will the golds be affected for the high temperature water? What's the highest temperature for the golds to be happy?... THanks.
