Overcrowding?

[Alvanck]

Wondering if this is good for this small tank or if it’s over crowded? I like having the cave. Corals and anemone will be added eventually. Don’t want to over crowd. Thanks!

I think it's up to personal preference. I don't think it's too much, but you might profit from breaking the rocks apart and using some reef-safe cement to build less bulky structures.

If you are planning to add something like a bubble tip anemone (which would get quite large for your tank), you might want to create a little island. They don't like walking over sand and this is a decent way to more or less force them to stay where they are. This way it won't walk around and sting every other coral to death. It's also a good way to make sure other corals like certain Zoas or even worse Green Star Polyp (GSP) to spread over your whole rock scape (don't put GSP, Xenia, Rhodactis, or similarly fast growing corals on your main rock).

Another thing to consider would be hiding spots if you are planning to get fish or shrimp. The cave is cool, but you can look through it and it doesn't provide an actual place to hide. You can maybe build another small cave by using some smaller rock pieces and the backwall.

It's your tank and you have to like it. Others like me can just throw in some ideas
