a question about the River-Tank Manifold Design

[gorhaf]

I want to set a 55 up like this and set it to 68 degrees, My question is would my Dojo be happy in these conditions and would a 55 be enough for 6 Dojo and 6 hill stream loaches. Possible a few rosy barbs just for a contrast. Any ideas or thoughts let me know also what kind of filtration would work best in this sort of tank or would the manifold be the filter sorry if that's a stupid question I am still new to a lot of the concepts in dealing with more exotic fish (I include the hill stream loach as exotic just because they are hard to find in my area and to make them happy and healthy (why get any animal if you aren't planning on doing that) it takes this extra step. and if they are half as satisfying as my Dojo then they will more than be worth it to me. What gph powerheads would i want to use for a 55?

Well I have 4 dojos in a 75 along with 4 giant danio and 2 gourami and even that feels overstocked. I'm scared to add anything more since the dojo loaches WILL grow, and even at their slow growth rate they'll eventually be 8-10 inches each. That's a lot of space. They seem to be a heavy bioload so I'm not sure you'd want so many potentially large fish in only a 55 gal.

6 Dojos will need more space than that. They will appreciate a certain amount of water movement, but a properly set up tank for Hillstreams has too much current for them. They're too big and boisterous to house with little hillstreams too IMO.
