I've got a tank of 7 Stendkers of mixed sizes/maturity. All's been well until about 3 weeks ago when the largest and one of the others larger (although still quite immature) fish paired . This caused the smaller 4 to hide away and not appear to eat. One of the pair (assumed to be male) is also very aggressive to the other large discus, who seems unfazed and gives as good as gets still eats well and does not hide away. The pair have spawned but the eggs disappeared after a couple of days. I've just noticed the female discus laying her eggs again on a rock but the male is eating them as soon as they pop out. My main question is how do I settle things down. I want the smaller fish to start feeding again as they were growing quickly and ravenous, they now just hide away and I've not seen them take food for weeks. Not so fussed at the moment about the spawning. I'm thinking if i stop that then all should return to normal? Would adding another large discus help? Any advice appreciated.
