Hey all, it looks like i am going to be getting a 240 gal setup that has i think 5 piraya, 4 5" and 1 4" already with it. My question here is would it be ok to add 3 caribe (5") and 2 super reds(4")? I know if I did i would have to re-arrange everything but is it a good enough chance of working to risk the money? Also, I'm thinking of getting a rhom. Is there a difference between where the specimen is collected? I see everyone says where it was collected, so does it make a difference? Like a real difference, not just reputation. Also, how long would like a 40-50 gallon tank last me? I am thinking I will just order a rhom when I order thoese other fish just to save money on shipping. Thanks a lot guys.
