Big home for my fishy

### ⭐⭐⭐⭐⭐ great tank
*by L***Y on 9 July 2026*

This tank (in my experience, twice over) comes packaged really well. No breakages or scratches. It’s really good quality, no leaking and opens up great possibilities for a tank. My only issue is buying it off amazon adds to the price a little, I’ve heard buying it straight from the manufacturer can be slightly cheaper.
