Max and Mina have interesting fish in their aquarium (a real one, not the ghettoquarium) – besides Pleco, the armored catfish from South America (algae eater Hypostomus plecostomus), who came with the tank from my in-laws, I decided to only stock native fish.
The first inhabitants were 5 marbled sand gobies (Oxyeleotris marmoratus) that the nanny brought from her bi-annual fish pond draining. These are actually one of the most farmed fish in SE Asia and are good eating, but I requested them specifically because I’ve seen how hardy they are – before we had an aquarium, the nanny brought a goby (local name: pla boo) that escaped from its bucket and lay on our tile floor overnight and survived. I now know that was possible because the marble goby oxyeleotris marmoratus activates hepatic glutamine synthetase and detoxifies ammonia to glutamine during air exposure (thank you internet and Singaporean fish nerds)
The second inhabitant was a bronze featherback (Notopterus notopterus) that the nanny’s husband caught in the pond across the street from our house, perhaps nine inches long. Watching a featherback swim, with its long underfin undulating, is like watching a dinosaur – almost scary on a primal level.
Unfortunately, this fish was kind of an asshole and would constantly try and start shit with the other fish in the tank. The thing is, it’s mouth is small and doesn’t have teeth, so it can’t really do any damage, it would just hone in on one of the other fish and peck at it for a while. Pleco, in particular, hated this guy. They would have these long, drawn-out fights with no conclusion because neither had the right kind of mouth to do damage with – I just recently read that Plecos can attach themselves to larger fish, but it never happened with mine AFAIK. In the end, I decided to give the other fish a break and threw the featherback back into the pond after snapping some photos.

When you were Mina’s age you were creeped out by plecostomus and absolutely hated seeing its mouth vacuuming up algae on the glass. But that featherback is absolutely uber-creepy.
