Added Two New Fish On Sunday, One Died Next Day.

TBH I'd say the botia was most likely unwell when you purchased it, These fish are super hardy IME and if Rummynoses, which are a super sensitive species are thriving in the tank, (strong vivid colours) then I'd guess that it isn't a water quality issue.

were there any symptoms that the botia showed before it died? apart from the lying on its side and breathing quickly, which is not unusual for botias (providing there is no ammonia and a high level of o2 in the tank)

Hi. Thanks. Umm. It would dart around madly, then stop and stay still for quite some time. Whether that's unusual or not I do not know. Seemed to like forcing itself into the smallest of hiding places. Wondered if it had got stuck a couple of times in one place. But then would reappear. Aside from that no observations that I'd say were unusual.

Did you look at the body after you took it out?

Was there anything unusual? Bloating, discoloration around anus...etc...? Anything?

Hi, yes, did take a look at the body once removed from the tank. Could not see any bloating, colour appeared as it was on the day we bought it, perhaps slighlty paler. No signs of reddening anywhere.

For botine loaches (such as yoyos), be very careful when netting them. They have deploy-able eye spines that can be caught in netting and cause serious trauma to the fish. Most fish shops don't seem to realize this and are pretty rough with them.

IME, they're very hardy once you get them settled into a tank. If they make it past the first couple days, they're good for a long time.

Other things to look out for with them is internal parasites and malnourishment. I've seen many at fish shops that are nearly starving. They should have bodies slightly higher than their heads, or equal in height. If their head looks big, don't buy them.

This is a healthy fish

Although not a yoyo, this is a very thin loach. Note the large head compared to the body size, and the pinched in stomach.

Not sure if that has anything to do with your problem, but I felt like throwing out some common loach problems
