im pretty sure its not the case as the yellow striped goby is now sick and both the lawnmower blenny and yellow striped goby are both really peaceful from what ive seen. I am pretty sure it was a case of brooklynella as the tank had it about a month and a half ago but I had treated the tank and left it to fallow so I thought it would have been safe to add fish again. It is possible the sickness came from the royal grammaThe gramma may not have enjoyed the 10g, it’s small for this fish who wants the claim a good size territory.
Maybe the result of real estate dispute?
im going to see what I can do about this but its really tough having to set up so many aquariums even if its the bare basic. I dont have an extra heater so I am not sure what im going to do (my spare heater broke)
