Hey MFK's Ive been looking at larger aquariums and stingray importers/breeders for a few months now and i decided to go with a 96"x36"x18" (270 gallon) tank. I plan on stocking it with one male and one female motoro to start. Im new to stingrays and large tanks and ill be needing some DIY filtration, probably a syphon running to a sump and back into aquarium via pond pump. I know rays are voracious feeders and they need excellent filtration. any other tips/pointers? things i should know. My largest tank is currently a 55 and i have no real ray experience. i have only done research and read up on them. The build should be done in about 4 weeks, then transportation, helicopter maby? and getting it into my basement.... lol should be fun.
