The Firemouths have been spawning almost continuously for over a year. The one in the lower-left corner is guarding a freshly fertilized clutch of eggs. The biggest one has been taking turns with her doing the same in that spot behind the wood in the middle of the tank. It’s around a two-week cycle where a batch gets laid and subsequently eaten by the catfish over the next couple weeks. Every so often they get two batches going at the same time and things get real chippy.
I decided to spend a couple minutes capturing some video after cleaning the glass last week. Still haven’t found any Garra Rufas to handle that little task for me since the last one died a couple years ago.
