yes definitely dont use any plants that are too large like that. your hairgrass looks to be the only plant choice that fits the dimensions of the bowl...this bowl could look great with hairgrass and some other very small plant.
You should do fine with a single ghost shrimp, but you're really unlikely to be able to keep more than one once they've grown out at all. If ghosts feel crowded, the dominant one will chase the other(s) right out of the vase.So far, evaporation hasn't been too bad - and I'm keeping it in a sunny windowsill. I've been keeping it filled to the top, and it loses maybe 1/3" of water per day, which is a lot less than what my open-top 3g loses.
I did originally plan to do a wabi kusa, but I've always loved the thought of having a teeny tiny aquarium...looking at this thing, I couldn't stop imagining what it would look like as a shrimp bowl.
Newman, I think you're talking about the wisteria. I plan to let it grow out of the tank and be a semi-emersed plant. (Also, the wisteria in my 3g is having chronic problems for unknown reasons, and I might need to replace it with the healthy cuttings in this tank at some point.) As for the foxtail, the piece in there is under an inch tall. If it survives, I think it'll be a nice addition. The thin, delicate leaves are just the right size for this bowl.
Any thoughts on ghost shrimp? Could I keep a few in this bowl?
