I have had Brigitte rasboras end up in the filter, they are maybe a little slimmer than the galaxy ones, they all managed to survive their day in the filter (a big ehiem). A sponge cover on the intake solved the problem.
Trimar are selling them at 10 for £25, and their delivery is a lot cheaper too. I trust Trimar to label their fish correctly online too, something I can't say about TF4U (no offence intended).
