Need some help please.
I have a tank which amongst other fish has 3 bumblebee gobies. They tend to keep themselves to themselves and are happy generally milling around the bottom of my tank amongst the rocks. They have been in the tank for about 3 months now.
One of them has gotten quite large and I am not sure if she may be pregnant? (having real trouble sexing them)
However the issue I have is that in one of my other tanks I had 3, but lost 2 about 2 months ago when I had a bad case of whitespot. Thankfully the white spot cleared up after about 3 weeks but sadly I lost a few fish.
There is only one bumble bee left in this tank and I am considering whether I should catch him and add him to the others or whether I should buy some more and add to his tank?
As the 3 in the other tank are settled would it upset them adding another in?
Not sure what to do for the best so would appreciate any advice you can give me
