hi friends i have bought a rio 180 fish tank then i bought 6 gold fishes in it(2 large and 4 small) is there any problem if i put tropical fishes in it by setting the temp to 26degrees
Yes, Gold fish are cold water fish, Tropical aren't and also you haven't cycled the tank so the Ammonia will probably kill them all...on top of that 180litres is pretty maxed out at 6 Goldifsh.
