New fish combo ideas will this work?

[SOARnTACO]

I have 125 dt and a 55gallon qt Bare bottom with just a small area of sand.

I want to get a diamond goby and a yellow head goby. For the qt and a blenney

The question is.

Will the gobys coexistence in the 55 qt?

Can I add a blenney since I have a tail spotted blenney in the dt already?

I would pick one goby and make sure it eats prepared foods. Diamond gobies don’t have a good survival track record. They tend to be territorial and will often fight similar fish.

QT will be an uphill battle if it’s not eating prepared foods and once you move it to a 125g the survival odds are better if you only have 1. Instead of the two, the one that tends to survive longer is the yellow watchmen goby.

I would also limit to 1 blenny at the time unless very small. Look into captive bred ones which may not be as territorial/aggressive.
