Ok, so i have a talbot damsel and because i only bought two at the time of getting them, one passed away due to tank complications around 8-9 months ago, this talbot has, over the past 2 weeks or so, become very very large. The only other fish in there that i could remotely see it breeding with is one of the cromis. Its made a little cove/cave and has begun building what looks like a nest but its so farfetched sounding to me, but thanks for reading and let me know!
