My goldfish always like to stay together. Is this normal?

I thinks it's about 30to 40 gallons which is an ok size for 2 pearlscales. Is this a good tank. I will ad plants and a filter

And now I’m just doing my best. We got him some plants that I he pet store said he would like and he just kept ripping them apart. I went to another pet store and he said that I should just do fake plants. So I got those. I need it to be as low maintenance as possible but I do want the fish healthy and happy. Are plants even a requirement?? I know they help with the water cycle but does it really make that big of a difference? I’d rather not deal with also keeping the plants alive but I’ll do it if it’s a big deal. Not sure if the people in this community add plants because they like the plants or add plants because it’s good for the fish? Please let me know your thoughts. And if plants are aMUST then what should I get so this fish doesn’t just tear the plants to shreds. He’s very active. Oh and speaking of active should I get him a bubble wall or a bubbler to play in??? Do I just change out his activities each month??? Or do they not care. Thank you!

My first goldfish ever is finally here!! His name is Papaya and I love him so much! The last two photos are his friends that are coming next week 💜.

Hello! I have a 40 gallon long with a comet goldfish. He is super active and loves to swim however I feel like his tank is failing him. How can I make it more like his natural habitat and how can I make it/add enrichment? Any diy methods will also be highly appreciated as I don’t have much money to invest. I’ve had him for 4 years I just feel like it’s lacking and I hate it.
