That is great about the 'hat' Juan, my kids are the same way, I currently have a cardboard based 'rocket ship' built from random bits of stuff found all over the house and probably a role of tape. Glad you figured out they were actually something you needed and that spot is now safe. Can't wait to see pics of what ever new stuff you decided to get. There are just so many things to choose from.
What is the deal with chromis, with the you get a school and still wind up with only a couple are they just that sensitive to changes or something. I bought 4 and only have the one that lived. Just a bummer because I really like how active they are and the whole schooling thing is my favorite.
In any case congrats on your first fish Juan, can't wait to see more stuff. And your pictures look great, so don't knock them
