[Singspot]

Hellow Everyone, do yiu have any experience with Yellow Watchman Gobi pair?

I read these can breed in tank and i want to try them: https://www.fantaseaaquariums.com/fishes-care/yellow-watchman-goby-care/

Questions (for a 240 Gallon established mixed reef 6 year old tank)
1. Are Yellow watchman Gobi compatible with Diamond Gobi?

2. If yes for #1, will a pair of Yellow watchman gobi be ok with a Diamond Gobi?

3. Anyone with any experience with pair / breeding yellow watchman gobi?

I have them in the same tank, 210g Red Sea s-1000. Haven’t noticed any problems. See the diamond all the time. Don’t see the yellow much. Think it’s gone and then it will peek out. Have a weaver gobi as well. Same thing thought he was gone then out he pops. Also have a lawnmower blenny in the same tank as well. Haven’t ever had them breed, had a pair of yellow but think lost one.
