We have several tanks but our pride and glory is the large 66g. It is currently a community tank but we've found that we enjoy our fancy goldfish tank better. Our thinking therefore, is to move all the fish out of the 66 into different tanks and put something else in the 66. What we like about the goldfish is their size and personalities. So... We want a species tank with the 66. A few large fish rather than lots of small ones as it is now. Any suggestions as to what will work/fit and how many. The fall-back plan would be another fancy goldfish tank but as we already have one, it would be nice to do something different.
