aT 5.30 am, DO NOT LEAVE A GAP IN GLASS TOPS ON TANK. I got woken at 5.30 this morning by some loud banging in the house, jumped up and couldnt see anything then heard the noise again and sounded like it was coming from my fish tank stand, couldnt understand what it was then couldnt see my big Flowerhorn?Red headed cichlid? And couldnt see him behind the tank? Heard the noise again and knew he must be inside the stand somehow. Turns out that he had jumped out of a 10-15 cm gap I left in glass lids, gap was at front of tank and he had got over light, down back of tank and into the only gap in solid stand that was only 13cm. I couldnt get behind and had to rush around finding containers for water as needed it back for other fish , then siphon all water out and then try move the still heavy tank. Finally did it, took 1 and half hours,was expecting fish to be dead but pulled him out and thought Id put him in one of the containers with airstone and he started swimming around. Wow , I was shocked, still carnt believe that he survived. Never thought they could survive like that outa water.What a start to the day.
