New 270gal landscaping

thanks, I had 3 of those, but I came home to find one dead. The only fish Iv know to just drop dead are the tinfoils. I had 3 regular tinfoils a while ago and all 3 just died, big boys to at 11,10 and 9" they were.
the same thing happened to me. my water parameters were perfect and they just started to act funny and drop dead randomly.
 
Very nice! It adds colour and is a little different then what most people do. Is that an ID shark in there?
