Okay, so I finally ran into my first hiccup as a beginner. I wasnt thinking and overstocked my 20 gallon. Well I was thinking, I thought Id have the money to upgrade tanks. Sadly aome financial issues has made that impossible right now. I was able to get a 7 Gallon bowed in the front, tall tank. Right now in my 20 gallon (more tall than long) I have a Powder Blue Dwarf Gourami, 5 lamp eye tetra, two silver tip tetra (which sometimes school with the lamp eye and get along very well), and an Albino BN Pleco. I knew I would have time to xfer since the Pleco is just at an inch. The Gourami is at 2 and 1/2 and the next biggest is one of my lamp eye which is at 2 inches long. They are very haply amd content. However, I know I still am overstocked, especially when they grow. I need to get them xfered before rhere is any damage. I was wondering what would be the best transfer? Should I let my Gourami get a tank of his own or maybe put the 2 silver tip tetras? Once I invest in a bigger tank, a 30 gallon should cover all the fish without exceeding the limit correct? Thanks in advance!
