Update: my gourami is now on his 5th brood. He must be exhausted. The dilemma is that if I leave the fry in the tank they get eaten, so he breeds again, and if I remove them he also breeds again. I don't have a breeding tank and I also find it hard to ID the right female to move if I did, ie before they have already made their nest. The best method of rearing for me has been removing the fry very early into a Tupperware in the main tank, until they grow enough to transfer Ito the small fry tank. The most fry I have is c 15 from the 4th brood, where I followed that technique. I have 3 or maybe 4 in my small fry tank, from broods 1 and 2. My infusoria just won't infuse, it's been long enough but I don't think it's warm enough or light enough in my Edinburgh flat. At night I use a lamp on it. I have 1 jar in a propagator, in case that helps. I'm hopeful the fry can transition from greenish water to crushed food and BBS. I have the good and bad fortune to have a green algae bloom in the big tank – I think from using liquid carbon? – which the fry like, but which looks ugly. Water changes aren't resolving it. I'm going to add some carbon to my external filter and I am adding more plants. According to advice here green water isn't affected by ferts, so I am actually adding higher doses of the UKPS Macro and Micro, on alternate days, hoping the plants can out-compete. I reduced lights from 11 to 6.5 hours with long sunrise and sunset (maybe these should be reduced). I will post about the green water if I can't resolve it. I also have some brown dusty algae on leaves and beech wood. I have ordered more amano and I am adding ramshorn snails from other tanks. I may get some otos. I'd had no algae problems in this tank since it started in May, but I got lazy with ferts, and then the liquid carbon seemed to trigger a bloom, which seems counter-intuitive. So much to learn...
