In the Fishtank was a series of EPs released by Konkurrent, an independent music distributor in the Netherlands. For the project, Konkurrent invited one or two bands to record and gave them two days studio time. The first four releases were recorded by individual bands, but eight of the last ten of them were the result of two bands (three in one case) teaming up to record. There were plans for more according to their website, but no new releases have come since ITF 15 in 2009.
