OK, I have a small ten gallon tank (my daughters room tank) It has a couple of danios, a tetra, two golden algae eaters, and a small cat. I have now gone through two plecos in the past 2 weeks. One was a rubber lip (tried this one since they tend to stay smaller and a common. Both died in a matter of days. Both were acclimated prior to going into the tank and all water levels are at a normal level. Nitrate, nitrite, ammonia, PH are all good. None of the fish seem to be ill. The plecos do not look at all beat up by cat which is the only one that I could think would even pose a threat at all. Could there be something that is poisoning the plecos. There is some algae build and is why I got one as the goldens do nothing but sit on the bottom most the time. The plecos get in the tank start going to town on the small amount of algae then are dead in a couple of days. So I know they are not starving as it is littleraly a couple of days. Is there any type of algae that can form in a tank and become deadly to a algae eater????? Not sure what is going on. Starting to think the tank is bad luck and should be replaced with a 20 (at least) I am beginning to hate tens as they seem to be harder to care for than my big tanks. Oh and yes water changes occur weekly.
Thanks
