    I've had three male guppies in a cycled 20G tall for 8-9 (or longer?) months. The other fish in the tank are 6 black skirt tetras. All the guppies usually swim together, but for the past few days one of them has been hanging out at the top of the tank, not swimming much. Water parameters:

    0 ammonia
    0 nitrite
    30-40 nitrate (hard to tell)

    I just did a 25% water change.

    He might be a little bloated? Scales aren't sticking up. I tried to feed him part of a cooked pea but he didn't eat it. I have him quarantined in a water pitcher right now hoping he'd eat but still no luck, though he does seem to want to eat his flaked food.

    When I opened the tank and put the net in he darted off, so he can still swim.

    Any advice? I don't have a quarantine tank set up. Nothing has changed in the tank in months - regular water changes, same food, same lighting, same filter.

    Thanks.

    Low oxygen in the water or your tank is too deep

    Anyway about guppy’s do yours have like yellow patches on the white/light blue part of the body

    No yellow patches. I have an airstone - lots of oxygen I think.

    Was he an adult when you got him?

    What is that red thing by his anal vent? Is it color on his bottom fins or something sticking out of his bum?

    JamieLu - That's the color on his bottom fins.

    FeederGuppies - I got them all from PetSmart, and best I know they were adults - they haven't grown at all in the time I've had them.

    Could be old age. Watch the other fish for any odd behavior.

    FeederGuppies, I suppose it could. I guess I assumed that the chain pet stores had enough turnover that what they sell is fairly young, but I have no reason to think that other than a guess. This guy doesn't seem unhappy or in distress - he's just not moving a lot and staying at the top. If I put a net in the tank or open the top just to look, he darts off with the other two guppies, but within a minute or two he's back up top again. Fins are moving enough to keep him in place, but that's it. No fin rot, no discoloration.

    Light is on about 6 1/2 - 7 hours/day. It's the standard light in the Aqueon 20G high hood.

    I forgot to update. The guppy died 2 days after posting this thread. The other 2 guppies periodically kept checking on him almost - circling up to see him then darting off. I think FeederGuppies was right - probably just old age. I checked him over after I removed him from the tank and saw no physical signs of disease.
    I'm down to 2 guppies in that tank now - debating whether to add 1 or 2 more. The 2 I have get along well, but I read that they should be kept in groups of at least 3?

    If they get along, there's no need to add another one. If you do, make sure the other fish in the tank look healthy, since guppies are pretty susceptible to disease.

    Thanks. Then maybe I won't rock the boat. The tank has filtration for more, but I almost hate to disrupt a good thing.
