I think I may have a problem. I've just introduced a 9' plecco (Pterygoplichthys gibbiceps) to my 50 gallon, well established aquarium that is also home to three 4' goldfish. It's been day four, and he sleeps all day in his favorite cave, and for the first two nights, I could watch him darting around as soon as the lights went off. These last few nights, he's been a little sluggish getting out of his cave, so I've been placing his algae wafers in the top hole of his cave to make sure he was getting enough to eat. The resulting mess confirmed he was indeed eating, but tonight, as I turned out the light, he was again shy to get out, and when he finally did, I noticed he seemed thinner and less active than before. I've tested the water chemistry, the temperature is a steady 72°, and the tank is free from filth. I was told by the shop where I bought him from that he was an owner trade in, as he got too big for their 20 gallon tank. He was a very healthy specimen! Could anyone shed some light on this behavior and weight loss issue for me? Any advice would be appreciated. Thank you in advance!

    Hard to say what's going on, he may still be adjusting. It wouldn't hurt to do a water change, especially since you're sure he's been eating, because all that food may be putting quite a load on the tank. I also suggest you test your ammonia, it can jump when the nutrient load is increased because the biofilter takes time to adjust to a higher load.

I just got a Glyptoperichthys multiradiatus and Hypostomus punctatus that's about 5 years old. Put him in my 55 gallon tank with maybe 5 tiny fish. He's just laying there on the bottom, he seems to be breathing fine but his fin is laying straight down on his back is this normal? Not much movement is it because he's old?

Is it normal for a pleco to stay on its back for 5 - 6 hrs? I thought it was dying, then all of a sudden it went nuts (swimming, jumping, diving).. now it follows me when I pass the tank..

    That doesn't sound exactly typical, but it sounds like he is doing fine now. Just keep an eye on him to make sure you don't see any other signs of illness. Also do the recommended water changes (about a fifth of the tank once a month) and check the water quality and temperature.

    Pleco's are generally very hardy, a week suggests it may have had issues when you bought it. Talk to your supplier, they may replace it for you.

I've noticed my little suckerfish going up for air several times. I'd not seen him do this previously. Am I worrying with reason or is this normal behavior?

    They do this at times to help maintain bouyancy.  Also will do it when water conditions may need to be tested.

About the breeding. This happened completely by accident. I have a albino bristlenose longfined pleco and an albino pleco and they just had babies. There are about 18 of them and they are about the size of half a pea. They are pinkish orange and I can already see the fins. I find this to be quite the experience since they are in a 35 gallon tank with a variety of chilids.

Hi, um, my senegal bichir is in love with my pleco and I am very confused. P.S. my senegal bichir even brings the pleco its food if it isn't close enough to the hiding place!

    AHH doesn't make much difference if you are confused - they don't seeem to be. No one tells an animal/fish/bird how to behave and they frequently behave outside what we think is the normal for the little fella. My daughters dog (big one) sleeps with the dwarf rabbit. My Queen (conure) is in love with my macaw. They're happy - why worry.
