I change morning and night same as spawning water change's on type being spawned,so alot of babies may need alittle etc.
I will only try to clean in front of cave if male is facing in other wise will try on next change.
Try to keep with normal feeding,lights,cleaning etc as fish may get jumpy if turning on lights early or later than usual etc.
Each tank stocking needs different changing so keep a record of amounts etc so if it works stick with it ( and if it didn't try changeing/fildling with this or ask on a forum some may tell others ? )
If eggs are kicked out place in to a tumbler. ( or find a male that will do a better job )
Water on changes should be close to same as tank when eggs are present if possible ( 1-4 under seems fine on my systems but yours may be set up different from mine )
Be mineful to use same water as always when small fry are present as they don't have the strenght until older to deal with large changes in water readings. ( ro/tank/tap can be very different so testing water before use should be done before any water change )
