So I have a tank of Metriaclima Zebra (lundu) Cichlids about 2-3 weeks ago one of them had some fry, almost all of them died only 4 are left now but I just noticed it has eggs in it's mouth it's tumbling again. What I'm wondering is when should I get the babies out because she's had a fat neck since the first batch and honestly I have no idea when eggs appeared?
