Those sound amazing!
I’ll save you some time hahah
I accidentally cracked the 75 on the way home when it hit the side of the car (whoops


) but I think it probably would have still held water since I couldn’t really find the crack anyway. But I never tested it and ended up using it as a brooder twice

I ended up buying more 10 gallons and I had several bettas for a while

but for some reason I couldn’t keep them alive very long despite the planted tanks and awesome set ups which sucked cause I got really attached to them

so then I ended up just dismantling the inside tanks.
For the goldfish I bought a 110 gallon rubber stock tank from TSC and put them in there and it’s working well. But I didn’t end up putting them in it until last spring because I figured it was too late to put them outside. They’ve been thriving out there.
A couple months ago I added 4 more goldfish and put them in a small garden pond out front and they’ve also been thriving. They are already huge (compared to their original size haha still tiny compared to the older ones

) and they have really bright, deep colors

I love them.
I also added two plecos to the big pond at that time but I never see them. And I know about how it’s supposed to only be one per thing but it’s only temporary and I will be moving everyone soon when I move.
I do also have another stock tank I bought when I turned my brooder into a fish pond

used this one once or twice and planning on making it another fish pond as well. Plus I have a hard pond liner thing still I’m considering using.
So yeah.
