Hi guys, Just wanted to ask a few questions about Pterodoras Granulous
1.Will it show aggression to any of my Fish?(In my signature)
2.Will a 370Gal house him for life?(will be upgrading in a few years)

3.Are they expensive?
4.Are the Albino Kind Really Rare or could i pick one up if i looked very hard?
5.Are they Fast Growers?
The 370Gal is 8'x3'x3'
