The purpose of the Egg Tumblers is to allow freshwater to circulate over eggs that have been removed from the female mouth brooder. A fresh supply of clean water allows fish eggs to develop in an oxygen rich environment and where fungus development is suppressed without the use of chemicals. Incubation occurs in the same aquarium where the fish are breeding to provide identical water conditions during incubation period. Egg Tumblers create a gentle rolling action to simulate the normal incubation of these fish in the females mouth. You should only use non-adhesive fish eggs in the tumbler.
The reasons for using an Egg Tumbler are simple:
Save the eggs from parents that swallows or spits clutch after clutch of viable eggs.
Females with eggs in their mouths cannot eat enough to remain in top condition.
Moving females into rearing tanks is stressful and could be limited by the availability of tanks to accommodate them.
Females without eggs in their mouths can defend themselves better.
Females can also spawn again sooner after being stripped of their eggs.

- Strip eggs into a net in the tank that the female is going back into to prevent the slippery fish faling back into the tank.
- Only use a tool to open female’s mouths as a last resort. Tropheus and Labeotropheus can be difficult because of their under-slung mouths.
- Spend no more than thirty seconds stripping a fish. If the fish is difficult to strip then don’t do it.
- Once the fish’s mouth is open over the net, simply bobbing the fish in and out of the water head down will cause the eggs to fall out. The eggs can be seen easily in the open mouth, so check every few seconds to see if there are any left.
- Occasionally some eggs get lodged back by the gill plates. But raising the gill plate gently will usually dislodge them.
- If an egg will not come out, I leave it there.
