Did you say 6 (six) children? Like you had five, then had another, then got a saltwater fish tank? ;Greedy;Hurting

I don't know whether to fall to my knees and praise you for unparalleled patience and tenacity or to reach out and try to alert the relevant authorities that there's a crazy guy on here.. lol.
You're going to need to do a massive upgrade! IMHO, you'll need at least a 6', pedestal style tank just so there's enough room for the whole family to sit around and look at it together!!
Seriously though, welcome to you, your family, and Atlas.
