Solomon,
I understand that i have a lot to learn (we all do), but 99% of the time when i speak it IS indeed from my own personal experiences and it is always to the best of my knowledge. There are two species of gar that i have not kept and one that I really have no desire to keep at the moment. Out of the 5 that i have kept (You guys say there is little to no difference with the husbandry between the Florida/Spotted gars, so i'm grouping them together) I have kept them all together. I also do have a good understanding for the Cuban Gar and im 100% possitive i could keep them with little to no trouble and i would put them in with the group that i currently have. That being said...the advice i gave above is exactly what i would/will do when i find a Cuban and grow him to the appropriate size. Of course this will all be incorporated into the soon to be 8' x 3' tank they will be housed in. You are correct in many ways, but when it comes to giving advice on housing gar together...I feel plenty qualified to give my 2 cents.
Also...you are correct, i have only been keeping gar for a few years, but i feel I have learned a TON of great info in those few years (many thanks to you and Richard, but i have learned nonetheless).
