That is a very cool little tank, do they no longer sell the 61-C? I can't seem to find it on their site, what are the dimensions?
I'm not sure what I'd do, lots of fissidens and some branchy manzanita sticking out the top maybe?
Thanks. Yeah, when I purchased it was the only one left.
Dimensions are: 24" x 24" x 12" at about 30 gallons.
My other tank in the same rooms has "manzanita sticking out the top" also, so I'm still debating rocks instead. Who knows.
