I'm not gonna lie, ultimate blues are pretty damn stunning. I didn't find out about them until after I had purchased Gorillus blue's. Or else I may have ended up with UB instead.
No, sadly I had repeated seal problems on my big tank. And eventually had to give up my two remaining umbee’s to a friend with large tanks. I have a large outdoor pond, and a 180 with a pair of very very old oscars and a Severum. But that’s it for me right now.
