Yeup, I grew up in Chino. Freshman in HS? You're exactly my bro's age. FH can be pretty expensive for a HS kid. Not just the price tag on the fish, but also the food, and the med. Keep your water clean for all your fish to avoid medical bills and headache. I had only guppies and goldfish to play with at that age LOL. If you are just starting this as new hobby, 60g with 1 FH is a good start. And if you do decide to get another FH, I would use a divider 1st to make sure things are cool, there is always a chance for you to leave it there permantely. I grew one my FH to be around 10" body length in a 60g with divider, then I traded him in for a female reddevil and a JK.
I've also heard the same thing long time ago, FH likes to live in smaller tanks, I think its mainly to piss them off so the color would show up better. But, I think mine are happier in my 100g than my 60g. FH can change their color depending on environment: background, substrate, mood, food, etc. I find the male to display their best color when it's courting a female.
Ohh boy, I typed too much. Glad to be able to help.
FH Experts, please correct me if I am wrong with any of my comments, I don't want to give him the wrong info. Thanks
