Last two pictures
I would move the crypt further away from the lotus, crypts tend to have huge root systems and it may overpower your tigerlotus. I have had to do the same thing because the leaves were overshadowing the base, which I was afraid would slow the growth of newer lotus leaves. and again I didnt want them chocking out the lotus.
Thanks for the input. I kind of figured as much, but I thought i could at least get some ideas. You tank is super-awesome, though!Really hard to say before things grow in...that still has the squeaky new look to it.
