Awesome but... – Fish Fingers! 3D Interactive Aquarium Review

I really love this app but I put in a bunch of tropical fish and now I want to change it back to some freshwater species but the fish don't even show up!! :( And if I put it as a random fish the blank version of the Scissortail fish comes up and it never finishes loading. Does anyone else have a problem like that and if so can you plz tell me how to fix it?? Because I'm getting a little sick of all the tropical stuff :P
