I keep a lot of inverts that I catched, trying to match the temperature of their natural habitat
And today I got a little bit lower by accident but it's something that I've been waiting the whole time for, in December it will probably be 11°c so I'll post it too.
I'm very happy about that I guess
And yes this is a saltwater (ignore the yellow water it's kinda like that but also because of editing the pic to see the thermometer)
