That could probably work right there, it'd be easier, and then, when the piranha outgrow the 50, you'll have bigger accomodations by then.
My question is:
If it's only a one or 2 yr plan, where are they going to go after a year or two? are you going to sell them, or upgrade? If you plan to upgrade, it's better to do it sooner rather than later, because plans can easily fall through...
That's why I keep referring to LIFE instead of the next couple of years.
I would hate for them to be in cramped quarters because it wasn't taken into account their adult size, lifespan, and knowing how long they were going to be a part of your home....does that make any sense? ^^
