Fisher suffered a disappointing 1-0 defeat to Deal Town at St Paul’s on Tuesday night.
Ben Chapman scored the only goal of the game in the fourth minute as the Fish’s three-match winning run came to an end.
Also in the Premier Division, Stansfeld ended their six-game losing streak in style as they defeated Punjab United 4-1 at Foxbury Avenue last weekend.
Dan Parkinson scored the opener in the eleventh minute and Rob Hughes doubled the lead two minutes later to set the hosts on their way to just a second win in thirteen games in 2023.
Tommy Whitnell made it 3-0 in the 38th minute before Paul Vines pulled one back twelve minutes into the second half.
Bu Alfie Moynes made sure it would be a comfortable victory when he added a fourth on 78 minutes.
The Stans are thirteenth in the table, level on 39 points with twelfth-place Fisher.
In the First Division, Bermondsey Town couldn’t add to their two league wins all season as they were defeated 2-0 at Forest Hill Park. Scott Jarvis in the 73rd minute and Ade Onasanya five minutes from time got the hosts’ goal.
Fisher travel to Welling Town this Saturday for a 3pm kick-off.
Stansfeld are away at Lordswood at the same time.
Bermondsey host Staplehurst Monarchs at St Paul’s, also at 3pm.
