this one is my 150 gallon, My parents wouldnt let me bring my 350 back from school when i got my internship so i had to scrable and find a big enough one to keep them in till spring.
rays eat them as well, its quite a sight to see... arowana takes them from above and pushes them toward the bottem and then the stingrays pounce on them.... im trying hard to get a pic of one pouncing .... but they are pretty quick
