Hermit Crab Sponge?

...my dairy cows and pandas are no more. I'm an idiot and I drowned them all on accident. I hate myself for it and I want to try again and am telling myself that they had exploded in numbers until I got heavy handed with the sprayer. I just figured that more pods would need more water. I was so proud of how I was doing on just six months! I don't want to do this again so I won't spray them as much but now I'm afraid of under watering. What about hermit crab sponges? They wouldn't be in standing water...but it would be safer, right? I have plenty of moss...but the moss directly touches the dirt and I'm afraid I'll flood it. Or should I just ball some super damp moss in a dish?

I just wanna do better. 😭
