Well ive recently been through a situation that leaves me with rebuilding my house from ground up. One of the positive things about this is now i get to do what ive always dreamed of doing. Im a complete newb to marine sharks and rays, so please feel free to give me any ideas that would be awesome. Im thinking about doing a 300 gallon tank built into the wall. Maybe even having all the plumping down in the basement so it could be viewed from two different rooms? I want sharks, i searched through the stickys escpecially the tank reccomendations one but honestly ended up getting a lil confused. Trust me im not going to just jump into this not knowing anything, it will be towards the end of spring when its actually getting set up. So theres plenty of time for research. If i was to go with a 300 which that can change, what sharks can be housed for life in that size and what sharks get along. My lfs guy used to live down in florida and worked with rays and sharks for 10 years, hes trying to get me into wanting the blue spotted ray in there also. Yes im sure to everyone else they are sweet looking. But from what ive read from u guys, they are not an easy one to keep. I am not looking to get into something that is over my head. I love predator fish, eels sharks rays etc. Ive also read from u guys that rounded edges are a need for sharks if i understood correctly? ive seen a lot of shark tanks that are the typical rectancular style. ideas, reccomendations, opinions are all welcome!!
