Well, I originally posted here about my bloated pleco and learned a lot about euthanasia and fish but did not do it. Our pleco hung in there for several weeks but never seemed to recover after deflating. He didn't eat much or hide or swim. But he didn't seem to be in pain (how does one know?) and he finally died during the night last night. My son is devastated but we will bury him outside and put a nice painted rock on his grave. It's a good lesson for him - he has lost lots of fish but this one upset him the most - maybe because it is bigger? I will not get another one because our tank is 20 gallons and I've learned that this is just not adequate for a pleco. I'm thinking chinese algae eaters (the algae is getting out of hand!!!)? Is that the same as a 'dwarf suckermouth catfish" as we have listed in this book we have? Anyway, just wanted to update you on the bloated pleco! Have a nice day everyone!
