Been looking at that too. Honestly i was going back and forth between the rose clone and the otm aqua v2, based on other threads. The only problem is the height though.
Can you modify it with another tank? I was thinking that some of these nano kits and whatnot might fit? I wouldn't mind getting two rta's if i could use parts from one to make, say, the rose or aqua smaller.
Honestly, the Aqua is pretty compact. I'll post a pic this afternoon of it and the Rose. Right now its nearly impossible to source a stumpy kit for either the clone or authentic Rose, sorry. I love them so much though, I don't care about the height.
