I have an Evolve 8 with a toilet bowl action going on, and I've been trying to come up with a fish that can take the fairly strong current (even with a baffle). So far, it looks like White Clouds are the best fit for that, but it is only 8 gallons max, and I've got dirt and glass pebbles in there, taking up a couple gallons of space. Would they be ok in such a small box? Also, I've got temperature issues as it's quite warm here in the summer. The lowest I can get the water is 75 degrees, and sometimes, it can go up to 80 degrees when it hangs out around 109 outside as we have single pane windows. Is this just too rough a situation for them?
