So my friend got "inspired" and bought a $50 show quality-ish ranchu. ...and put her in a 5g tank she originality bought for mosquito rasboras. This was back in April, and the poor thing's been pooping stress eggs non-stop. She's about 1.5". And for family and monetary reasons, my friend can't upgrade without causing drama - and tbh isn't trying very hard ...but 5 gallons for a goldfish. Really. I picked up 10g for her from the thrift store - gonna wrap it like it's a box full of stuff and smuggle it, and help her set it up. The idea is to swap 5g for 10g and just.. pretend it's the same tank lol. No drama. The dimensions are kind of similar, so we're hoping her aunt won't notice. $5 Canadian is about $3.50 USD. Best venti Starbucks latte I didn't buy! Wish I could do more. Share your stories with that one friend we all have.
