Diamond Goby Concern

[Mark Gray]

Sorry about your loss I have a 55 with a 39 gallon sump, with that many fish you maybe need to test your water and I think I would be worried about the Oxygen like everyone else said too

Starvation wasn't the cause of death based on your description, it was just another factor to consider. If that one wasn't getting enough food, it is likely that others aren't as well. This is really where you're going to see the size of your tank isnt sufficient to keep what you're trying to do. You don't have the equipment to support the inhabitants you have; you've put too many fish in too little water. If you feed them more, the water conditions become worse (assuming lack of oxygen is the main issue at this point which seems likely). Hopefully this isn't followed by more dead fish in the next 24 hours but I think that is where you're heading unfortunately.

yes, I have a 55-gallon with 4 firefish gobies, 2 clown gobies, 1 ruby red dragonet, 1 powder blue tang (that will be sold when he outgrows his tank!), one Rainford's goby, and a maroon clownfish. Its a full house of gobies lol!! I cant screen my top because I have tubing and other things going over the edge. I do have glass doors that cover most of the top but don't have a screen top.

Kelsey,
That's really a big bio-load for a 55 gallon.
It probably time to re-test your ammonia, nitrites and and nitrates.

Sorry ;Sorry about your loss and we all live and learn, the hard way
