just had a funny thought...
one year when i took care of some troppys for the aquarium in the winter (we are seasonal) i got a little ten gallon and had a juvenile blue angel, a sea robin, a northern puffer, and a shame face crab. when the angel came up to the glass looking for me my dog jumped on the bed and would headbutt my tank.
LUCKILY this tank will be further from my bed... hopefully not frenchbulldog length.....
that last tank was acrylic good thing
