I've been reading a lot of older posts, trying to learn all I can. Acei's are recommended by everyone as a great starter fish, etc. They are also listed on the cookie cutter page for 55 gallon tanks. In a lot of posts people are saying they eventually outgrow the 55 gallon tank and will need a larger one. I was planning on having Acei's as one of 3 species i'll be putting in my tank. The thing is I don't want to upgrade to a larger tank, I have no plans for that. I don't want to put any fish in my tank that will need a larger tank at some point. Should I still get Acei or should I find a different species that won't get quite as large? I'd appreciate any opinions, thanks.
