is that tank 13" or 15" wide? looks to be a tall skinny tank so i wouldnt suggest anything over 7-8" fully grown.
ive been considering an orinoco dwarf pike for my community. really cool looking fish but ive never kept one. raphael catfish are also a good size bottom feeder for that tank.
cool tank though. i lile the curved corners. is that a truvu?
edit: i just saw the bit about how its a grow out tank. if i was starting a predator tank I'd stick with pike cichlids and some cool catfish.
Its definitely a tall skinny tank measurements 48" L x 15" W x 27" H
Not sure what tank it is really it was a eBay purchase, no branding or anything on the aquarium but i do like the curved corners looks great in my living room.
Pike cichlids are pretty cool fish
