Suppose I might as well share this, it's what I put together for crinoids.
This applies to just about any creature and their safety is what matters.
Also over time it will be a safe-haven for pods, a buffer for any bacterial/algae growth, and it will help "clean" your water as it becomes colonized by filter feeders.
No, it doesn't look very awesome, but I NEVER have to worry about making a newb-mistake and worrying about creatures being sucked into my pumps. It also expands the flow to the pump over a larger area, so it outperforms a sponge cover.
You're welcome, and welcome to the hobby!
