Im new to trophs and 2 weeks ago I watched 2 females spawn and collect eggs. Never had mouth brooders before. So its been 2 weeks and I noticed some odd behavior. Or maybe its normal so I have to ask. The holding females both head to,the top of the tank, grab a bubble of air and head down to a rck to graze. They then seem to gargle the air arounfd then release a bubble thru gills. Rinse and repeat. Is this normal ? No other fish in the tank do,this. I dont think oxygen levels are low. Lots of surface movement and filtration. Tank is 75g with 2 petros and 14 trophs so stocked a bit heavy but a very healthy and active tank. What the heck are these females doing ??? :lol:
