YES, that is exactly what I am trying to figure out. Thank you Shark. I obvious care very much about these fish and want to give them the proper home that I can provide within reasonable investment and efforts. I know bigger is always better and I will love to get a tank like what DJ shared, but if I can get away with 300, I wouldn't go get a 500, and if I can get away with a 180, I wouldn't go get a 300, etc. even if I can for these fish. Trying to fit their minimum or better than minimum space requirement, hope I am expressing it correctly. Hope that make sense. Based on what you said, it does sounds like 6 foot tank might be a little short for these large fish and even 7 foot seems no long enough. Then the question becomes is 8 foot or 9 foot really long enough to make them truly happy.
I am trying to find the most affordable and realistic options that I can find that would allow me to keep these fishes long term and thriving. Based on everything I am hearing so far, it doesn't sound like there is an definite answer.
I was looking at 6 footer and 8 footer and didn't realize there are 7 footer. Will check and see maybe there is a away to squeeze a 7 footer in.
I realize maybe I am asking a question that simply has no answer but really just hoping to have someone who the actual experience, good or bad to share.
Thanks
