I can understand the concerns about the "snagging potential" of the spider wood... I think before a splendens gets added, I'll pull the wood out to my wood work bench, and grind off the small pokey pieces, and soften / round off the other parts that stick out... I've not scaped it yet, but I'm sitting 6 feet away from it right now, and can watch the cherry shrimp swimming around...
I should have culled one, that is translucent red, not the deep cherry red... I'll pull that one out, but I have several large deep red shrimp in there now, and several babies, I can also see swimming around from 6 feet away...
the Blueberry snails arrive this week ( if shipping is reliable )
