No, zebrafishes can't use chromatography. In general, fishes are not qualified as operators of scientific instruments since it is necessary to have hands for that.

OK, now for a serious answer: if you want to analyze zebrafish tissue with chromatography, you need to separate the completely insoluble parts of the tissue first, otherwise you will just jam the column in both cases.

For the analysis of the insoluble parts, you will have to do some sort of chemical cleavage procedure to make them soluble.
