Well some will say I am a little crazy and others will not, I really want to keep stingrays (I am just fascinated by them) So while planning for this tank and starting to think that rays would just not fit too well I was a little disappointed. Then the other day a 600 gallon tank that is perfect for rays became avail at a too cheap to pass price, So now on Thursday I will have a 450 and 600 gallon tank in the garage waiting on the basement being finished. At this point I do plan on selling the 450 because I really don't need and should not have both tanks, even though that would be super sweet. This tank is 120x48x24 so allot of footage for rays to be very very happy in. My only question is that he has a pump that is about 4 years old that he will include for the right price, to me it would be less that half the cost of new but I don't know too well the pricing of a used reeflo hammerhead. Nice thing is that it would be plumbed and ready to go with it. I already know I will want a 36-48 high tank later because I was starting to really like the tall tanks, but as for rays this is the best option. Now If I could only keep both which if nobody will pay what I got the other tank for I might but I really don't need that many tanks but I could sell some others and just have two. Thoughts and ideas always too many LOL, And its official I am a tank hoarder, I have two many, most without water in them.
