Portsmouth make double signing
Bean, 30, has found first-team football hard to come by at The Colchester Community Stadium so far this season, featuring just five times for the U’s.
Fish, 25, is in a similar situation, joining to get more playing time under his belt, having featured only three times for the Gills this season.
Pompey boss Andy Awford told the club’s official website: “They’re two experienced players, who know what is required at this level.
“We’ve had them watched and know what they can do – we hope that they can come straight in and make an impact.”
