I give that a very solid 9!!
Looks like it needs some sand space though, maybe be to many shells or deep enough sand? I don't know much about those though.
Overall great job!
Here's mine for a bump of a fantastic thread!! Keep it going guys.
Multifasciatus does not like sand. I see many people adding sand because they like the moving of the sand the multi's do. I had many conversations about this. In the original habitat they live in, they live on a huge bottom of empty Neothauma snail shells. They never get to see sand.
Anyway thanks for the nice words! I actually really like the tank you showed. Not too crowded and a nice layer of green algae, great!
