I have a 3g eclipse for my mantis shrimp. I like it mostly because it was easy to drill; I've got it plumbed into my main system. I know you can get better lights for it too. Maybe some day when the mantis is all grown up and out of the house I'll convert it to a full reef tank. I just wish I had bought the 6g model.
im not sure if the minibow youre talking about is the all glass one i saw online, but if it is, i gotta say the eclipse looks way better imo, especially in the hood design. I have a 12 gallon eclipse and its a great tank, changing the lighting was easy and the 12 is deep enough to do some nice rock placement, i say go for the eclipse
I found a 15 gal glass eclipse tank. I put the smartlight upgrade light kit in it. (32w pc 50/50 bulb) 15 gal has same footprint as a 10 gal tank but it's taller. I have yet to see any commercial lighting options for all-glass minibows. The smart kit is made with instructions to upgrade eclipse hoods. It took 10 mins or less to upgrade it.
