Hi, I’m wanting to get a baby snowflake eel for my 75 gallon tank. It has a secure lid and I’m making caves for him. The only issue is that my substrate is about 50% crushed coral and 50% sand. I’ve read that crushed coral can get an eel stuck in the sand or be difficult to burrow in.

Will 50% coral be okay for the eel? I’m building up a DSB currently so it will be more sand later, but there is still a large amount of crushed coral. Would adding PVC pipes to create tunnels solve this issue?

They have a slow digestion system and if any accidentally ingested could cause an issue
You can remove some of the crushed with a coarse net, not fine and expect a cloudy mess temporarily
