Will open a new topic instead of continuing my old one.
Setup - 360l, running for years, remade slowly ( months) - removed stuff (limestone, plants, shells), added stuff (plants, wood), weekly water changes, the usual. Ph 6,4. Temp 27°C
Till Monday it had 6 rasboras, 5 tylomelania, 3 bamboo shrimp.
Since Monday 15 hatchetfish, 15 corydoras sterbai, 20 ember tetra, 3 bamboo shrimp, 5 tylomelania.
I understand I did a large bioload when adding all the fish at once, but I did a water change right before and it is a stable tank and the fish are small.
Anyway, to the issue. Cories are ok, behaving nicely, curious and active. Hatchetfish are static, but they are ok, nice colors, they even feed ( which surprised me in an import fish). Tetras are not so ok.
Yesterday one spent all the time at the surface, at 45° angle, rapid movement of the mouth, mouth right at the surface. All tetras have rapid movement of the mouth though, even those in the school, but then again, thanks to cories a lot of floating particles in the water column. The shrimp are having a blast. This tetra did not participate in the school.
I removed this tetra just in case, though it may have caused it more stress. In the morning there is a fungus in its eye. I put a drop of esha 2000 in its quarantine.
Another tetra now also spends time at the surface at this angle, but it ventures a bit lower and participated in the feeding, not in the school. Will keep an eye at it, but should I remove it or wait for some fungus to appear too?
Last tetra is very bleak color (though not all tetras regained the color after the transport, 1/4 are still paler, this one is very much pale) and looks like the jaw is somehow wide, or the gills are open (they are not). Very strange looking, but it participates in the school and in the feeding. Will try to take a picture but am not holding my breath the tetras are always moving and not easy.
Should I act proactively and remove those that don't look perfect, or wait it out and see what happens?
