My CIchlasomas have spawned, I wasn't expecting it just yet as I only got them as babies in September (instead of the keyhole cichlids I had ordered). So this tank was initially a community and not really set up for breeding. But as they have spawned and are so far looking after the eggs well I would like to see if I can raise any of the fry. The filter I have is a Jad (same as Boyu) canister EF 45, rated at 1,400 liters per hour, it does not have an adjustable flow. The tank is 120 cm x 40 by 50 high ( about 4ft x 16 x 19"), 240l or 65 gallons approx. I am wondering if I can cover the intake with either sponge or a fine mesh cloth to prevent fry being sucked up, or will this affect the filter flow rate too much? I do also have other issues. Recently I have moved all my pencilfish and neons to another tank as they started to disappear and I blame the cichlids. But I still have one other Cichlasoma in the tank (I am trying to rehome it) and 2 male Apistogrammas that I could potentially move to the other tank, though they might cause trouble there, as there is already a pair of cacatuoides in that tank. So I don't know if the parents will be ale to protect the fry from these other fish.
