Rainbow Stiphodon Goby (Stiphodon ornatus) Oxygen in water?

[Brandy]

So I think I heard from @Dwayne Brown that these fish feed on mulm and biofilm, and the internet agrees.

I see lots of warnings that they need a high rate of dissolved oxygen at the higher end of their temp range. The tank I wanted them for houses angelfish and rams, so there is a narrow window of overlap right at the top of the goby's temp range--short of owning an O2 meter, is there any way for me to figure out how much dissolved oxygen is enough?

I have a 29g, heavily planted, @ 82 deg F and about a pH of 6.5-7.4. I run 2 large sponge filters with airstones and a lot of driftwood. The substrate is ecocomplete, and it might be 25% exposed, and mulm gathers faster than I really want to vacuum it up, or more often than I need to change water. I have thought also of adding sterbai corys or more khuli loaches. I don't want to add more tech to the tank, I want to work with what I have. I have considered a gravel cap, but I think that is a temporary solution at best. I have also considered Maylasian Trumpet snails or deliberately introducing live black worms...

Essentially, if you have an air stone. you'll be close to maximum saturation of oxygen.

Thanks, that was what I thought I remembered. 🙂
