I know this is an over asked question, but this is an unusual fish... Is this a breeding tube on my Rhinogobius maxillivirgatus?

Fat Homer Fat Homer Not sure if you breed fish, but you keep gobies...

There's a tuft of dead cyanobacteria that folded over on intself, near the top of the tank at the back, that I didn't clean off, and I noticed the goby in question and the male goby exploring it with eachother, which is uncommon because they rarely stick to the glass and typically just lie down on the bottom... I think something may be about to happen...

This species may also be R. immaculatus, but I'm leaning more towards R. maxillivirgatus, as the male has orange at the base of his pectoral fins rather than beige like R. immaculatus.

Any replies would be appreciated. I've only had fish lay fertilized eggs once, so I'm still new to raising fry...

tlindsey tlindsey If I remember correctly I think you have a bit of experience successfully breeding fish.

Most definitely looks like one is loaded with eggs. I personally never had any Goby spawn but from the unusual activity your describing sounds like spawning behavior.

I just spoke with Wes, and he said it's a completely landlocked, species, and he has a couple friends that bred them in the past, so it shouldn't be too difficult... This was a relief to hear as the fry would have been a lot more complicated to raise if they were amphidromous...

That's exciting! Any tips on raising the fry? I have hikari first bites on hand, is that a good fry food, or should I do something live instead? I'm almost completely ignorant on raising fry, so I'll need the whole run down.

I was hoping to set up some sort of system that circulated original tank water into the frys' tank so I wouldn't have trouble matching the parameters, and to make water changes easier, if that's possible. Also, the nitrates out of the tap are 20ppm, so that's the lowest they can get after water changes. Will that be bad for the fry? I can do daily water changes if need be, but I can't get the nitrates below 20.

I just added some river rocks to the tank, as I read that rhinogobius like to make nests under rocks. Hopefully he'll make a new under one of the rocks once he realizes the algae is too flimsy...

Excuse the tank... The plants died off a while ago and I just starting trying to get baby tears growing in the tank. I think I finally found a light/co2/fert balance that they like...20191001_211435.jpg
 
Never managed to get mine to breed so really not sure, however will be following your thread to see if you get lucky...

Sorry was at work. You have a planted aquarium which will provide some source of micro foods for fry. The Hikari First Bites probably won't be excepted by the fry. Live baby Brine Shrimp will instantly trigger a feeding response due to movement. Micro Worms would be another source of food and they are very easy too culture.

Thanks, I'll look into micro worms since they're easy. I plan to remove them from the tank though, as the only real plant in there now is algae, and it's a community tank with puffers and cories, so I don't the eggs or fry would fair very well... How should I go about removing the eggs?
