Hi all, A while back I bought 2 angelfish from a petstore. Both of them died from what was thought to be an attack from a pleco as tank parameters were perfect and no other fish had died. A few weeks ago now i bought 2 angelfish again, same place. Again, one has died, but i saw its symtoms this time. He started swimming sideways and all ways. With his mouth wide open. Like he was choking. Then eventually stopped swimming. Now the other angelfish looks fine? Cheers.
