I'm considering putting in a couple of White tips upon the recommendation of experts on this site. I will also put a Japanese Leopard Shark in there. As for the BTRs, I have good connections with the local zoo and aquariums and I was told they would gladly accept a donation as long as the fish is healthy and I give them a heads-up 6 months before the re-homing as they apparently have quotas as to how many fish they can house within each of their aquariums. Does this make sense?
After a long research, I have created a list of all the potential species that could go well in the aquarium, I will share this with you after I check their availability.
With regards to TNTtropical's comments to widen the tank, I would have loved to but this is the maximum size tank I can place into the designated area of the house. The acrylic has already been built (CLAX Italia) and is now being water tested.
I would love to hear more on what you guys think about the design though...
