375 gallon stocking advice

Hello. First time poster here, but have been browsing through many of the topics on this forum over the past several days. Definitely the best fish forum I have visited!

Anyways, by the beginning of next year or possibly sooner, I might be able to get my hands on a 375 gallon tank (dimensions are 96"x36"x25"). Cichla have definitely caught my eye, but first I was wondering if any of you would have any advice on how to stock it? I know these fish get huge, and I figured once they have reached 20" or so, I would probably be limited on how many I could fit. My initial plan was to attempt to stock it with 12 various pbass (excluding the real big guys like tems), and as they grow weed them out to my favorite 5-6 for my final stock. How many full grown pbass do you think could fit without being too crowded in a tank of this size?

I am also very curious to see some pics of your setups with full grown pbass or at least close to full grown. I've seen many beautiful setups on this site, but it's hard to tell if they were full grown or not. I'd like to be able to get a grasp of how much room is available in big tanks once these guys get huge.

Thanks a lot!

Yeah, I've read a lot on how these guys are real messy, but keeping up with water changes and feeding will not be problem as I am self employed and have a lot of free time.

Also, I saw that adult cichla thread, but not very many full tank shots that showcases how much room is available. However, there are some real beasts in that thread!

Hah yeah. I've seen feeding vids of these guys on youtube, and I think I'll have to save up a bit more money to get me a nice wetsuit.
