I have two lovely Discus who paired off and laid eggs - woo hoo!!  The best part is that my other half knows how much I paid for my fish and that I can sell them, so said 'I need another tank to raise them'.  Ohhhh - words you only dream about! 
 
Well two days later the other fish in the tank ate the eggs when the Discus wandered away for a bit.  But...a couple of days later they laid some more.  Day 3 I couldn't see the eggs so presumed they were eaten again but day 4 and I have a closer look with a magnifying glass as the Discus were still hanging around where the eggs were and I have wrigglers!!!  The parents are being very protective this time but once the babies start swimming are they going to be gobbled up straight away?  I don't have a separate tank yet - working on it. 
 
Ironically I think the wrigglers look exactly like the BBA - but with eyes when you look closely ;-) 
 
 
 
 
The other fish are: 3 more Discus, Rams, Cardinal Tetras, Golden Bristlenose, Corydoras Julli.  They are all in a med/heavy planted 350l tank with a Fluval FX5 filter, temp is 29 deg C, PH 6.0-6.2, Ammonia and Nitrite always 0 and Nitrate 2ppm - 5ppm.  The water is filtered rain water
