Hi everyone. I'm planning on getting a 6' or 8' tank soon depending on what is a bargain. I want to stock it with a shoal of clown loaches, a couple kinds of rainbows, and a few siamese algae eaters. Does anyone else have some suggestions for compatible tank mates that are a little on the larger size that won't harm the aforementioned fish? I thought of angels, but I'm not sure they'd do well with all the buzzing around the other species would be doing.
