after much arbitration as to what to fill my 55g with i've decided to try and shoal about a dozen exodons. However due to availability in my area and budget im going to have to buy them in small groups 3 to 5 at a time. Is this feasable assuming i get them all near same size, and bearing in mind i have a lot of hiding spots in this tank (pots and tall grass) or will the first batch just keep eating the newcommers? I'd appreciate advice.
