Don’t stress too much, but they are really hard to breed. Have you seen any females with tubes down yet? The agro might step up when that happens.
i feed mine a mix of bait prawns (cut in half) and pellet. I will not feed for a day or two before feeding prawns. Mix up the water changes a bit and don’t do any for 2-3 weeks then do Water change and feed prawns. Try a few different things.
I’d also try and settle on a breeding group and let them settle into the tank. Go with 1-2 males and 6-8 females. Always have a spare male in another tank if possible to give you options if needed.
I’m not overly fussy with my water. Straight from the tap into the tank, plus prime, cichlid trace, buffer.
My Moba first bred 8 years ago, I lost the WC male, went through a couple of F1s males that got bossed by the girls, I’m back to a WC male and they finally bred again. If you can get your hands on a WC male, I reckon it’s worth it
