It's literally a large nutella jar
my quarantine tanks are full at the moment and even then, they're reading 29° which is 84F. His tank was reading 86F so I scooped him out and put him in the jar under my sorority with an airline tube into it for some turbulence. Hoping it won't be too long until it cools down enough to return him to his tank, he doesn't know what to do with his coconut hut! I have salvinia in my sorority, but my plakats still try and jump so I dont trust it lol, they might just be little cows though! I've got some mesh kicking around, I'll see what I can knock up, I'll be left with no choice if it gets any hotter! Hope your little fishies are doing well!?
