Should I Worry?

[TotallyTropical]

I was looking in my tank the other day, and found my first (and favorite) Kuhli Loach floating at the surface, and I thought he was just playing around, because he did that a lot. But he looked like he was on his side, so I knew he was dead. He looked happy the day before! I checked the other fish that were in my tank (currently just 2 Otos and 3 other Kuhlis), and they looked pretty much okay, the Otos playing around, the Kuhlis huddled up all in one place. I only found it strange because they usually stay apart most of the time (they have some cute personalities ). I tested, and the ammonia was under .25ppm, but I decided to do a water change in case. Now, I just came back from a vacation, and I saw 2 of them, one almost completely white (probably my new-ish one), the other more shy than usual. I didn't think that it was THAT strange, but is this something that, like the title suggests, I should be worrying about?

I lost a kulhi the other day. For no apparent reason he was at the front of the tank (most unusual) lying on his side then suddenly squirming about like a mad thing, clearly distressed; I did the decent thing. My other five kuhli's are as hermit-like as always, coming out only at night and completely as normal. Sometimes they just get ill/old and die; as do we all.

Worry only if you lose another one.

PS Love your signature dog, so sweet.

Alright. The pale one returned to normal anyway today. I will miss him though.....
PS: Thank you! I love my big baby dog! She does that whenever she's bored, but she also dances and sings. Husky Border Collie mix, one of the most diva and high maintenance breeds.
Edit: she also does a "turtle" pose.
