Well, shall I say welcome back?? Hahah!~ Talk about a return with Gusto!!
That tank is gorgeous! And you did an awesome job with swift to the point explanations! I could learn a thing or two from you! HAHA!
I ALWAYS LOVED THAT OPEN TOP LOOK, THE WHITE STAND AND ALL, VERY SLEEK, SEXY AND ATTRACTIVE!
Good plan in place, sounds like you have learned and grown a lot and can apply all that to this new adventure...
My only real suggestion or issue would be mixing the group with the solo discus. I am sure you are attached to him, sick of maintaining a solo tank, and many other reasons . I just personally feel that tank with the strain you chose as a single strain will be stunning, adding the singled out bright patterned fish may just look off or strange.
Again, your tank, your fish and all just giving my opinion . Either way its a bute and can't wait to see the fish grow and get in there!!
