Actually, Brian, I do need to hear (read?) these things since I pretty much jumped the gun by getting these two in the first place. Unfortunately, I sold my 40 gallon, thinking I didn't need it and I could use the money more... Bad move. So the way I see it I have 3 options:
1) Buy another tank big enough for the discus alone. Would they be happy with just the 2 of them? And the hassle of doing water changes in a tank on the floor (underneath the 75 gallon) or trying to find room for yet another tank. And spending even more money...
2) Divide the 75 gallon. Do they make net barriers so that water exchange can happen? This doesn't seem like the most practical solution...
3) Sell or rehome the discus. This may be a better solution, even though I won't get to have the fun of watching them grow up, etc.
Any thoughts? The discus that was injured is basically completely healed, but there is still a whitish spot on one of its fins, so I'd like to continue treatment for another week or so.
