I've got a 29 gallon tank that's been running for about a month. I cycled it with seeded filter material in the HOB, a sponge filter than ran in one of my other tanks for a few months, bottled bacteria, and live plants from my other tanks. I added ammonia before adding any fish and tested to make sure it was fully cycled. After a few days of adding ammonia, the bacteria load was high enough to handle 2 ppm of ammonia in less than 12 hours, so I did a large water change and then added 6 forktail blue eye rainbowfish. A week later, I added 4 peacock gudgeons (3 F, 1 M). Recently it seems that the lone male went missing. The first few days I had them, all 4 of them were visible most of the time, but over the last few days, the three females are always out and about swimming, but the male is missing. There hasn't been a dead body and tank parameters are normal 0/0/10, pH 7.4, Temp 76 F. There is a chance that maybe one of the females laid eggs, but if the male is with the eggs, shouldn't he still come out to eat? I haven't taken apart the stack of rocks on the left of the tank to see if he's hiding in there. So... is it normal for the male to go missing for a few days, if he's hanging out by eggs? Would he still come out to eat?
