I don;t believe three would work in that size of tank. Two would be fine, with proper filteration
Yes but you would need to have lots of filtration. I have 5 single tailed goldfish in a 75 gallon tank however 3 of them are rescues that lived in a 10 gallon tank with pretty much no filtration and were underfed so they are all stunted. And one of the non recuses seems to have been stunted before I bought it so there is only one goldfish of a decent size in the tank.
True but I would go heavy with filtration. Just keeping two fish is the better option. If you would do three then lots of sponge filters and plants.
oh and also have a very thick substrate layer. Aim for at least 3 inches but deeper is better
I don't currently have any fancies, that's a long story. I do have two Comets that live in my turtle tank that have more than quadrupled in size since I got them. I used to have fancies (A ranchu, two telescope eyeds, a ryukin, and two shubunkins) that lived in a 75 gal. My dad did a water change on their tank and didn't put in dechlorinator when he put the new water in so that was the end of that.
I now have a few guppies and Mollies in the 75 gal.
Well, 8 guppies and 4 mollies. I had a few more guppies that have died in the few weeks for some reason. I do have around 30 guppy fry in a ten gal in my room. Their parents live in the 75 gal, they are just being grown out until they are big enough not to be eaten by the other guppies in the tank.
Okay that’s the other thing what do I use? Sand or gravel not aqua soil because the Goldie’s can choke on them.
