I'm thinking for the future here, tank isn't cycled yet. I was wondering what else could go in my 12 gal cube? 40cmx40cmx40cm I believe. I was thinking shrimp or maybe those Thai Micro Crabs. But I have a betta and I'm thinking he might eat them. He seems friendly enough though and I've never seen any kind of aggression come from him. So possibly. Any other suggestions are welcome, of course stocking has to be revolved around him and the tank size as usual. I jus kinda like a little more activity I guess. He's cute but at the same time it's a little empty in there. The current substrate is gravel but I could easily change it out if I went for shrimp or some other invert. (I hate gravel anyway haha) Just have it because it's cheaper than sand.
