No critters on my rocks

[seapony]

my tank has been running since September and i recently noticed that i don't seem to have any critters on my rocks. no pods or creapy crawlys of any kind.

should I be worried?

I also dont have any alge in my tank exept coraline alge... i'm happy about this but it dosen't quite seem right, all fish tanks have alge right?

all my fish and the few softies I have seem to be doing well.

Pods hide and best seen at night with red light. Be happy there's no pest. And as for algea your doin something right
