so i posted on the angel/discus forum but that place is like dead so thought i would ask here since im sure a lot of you guys keep angels as well as the big brutes. i just got in 6 wild caught scalare yesterday, 2 that were large with there bodies being about 3in long (not including tail) and 4 that were smaller with bodies like 1.5-2in long. well they all looked good when they first came in and they were packaged great and i slowly acclimated them over a period of like 45min-1hr. and then placed them in the tank with the lights off, the argentea was bothering them a bit (though no damage) so i moved him to my quarantine tank and then they were all acting fine, they even started to eat a bit within an hour of going into the tank. but then this morning i turn on the lights to find the largest angel lying dead on the sand floor. anyone have any idea on what could have happened? he was gorgeous and i was soo sad to loose him especially after he/she was acting like they were adjusting so well. my pH is a little high at 7.2 but i thought that, that level would still be ok, not sure on the exact levels of stuff in my tank but usually my nitrates never get to more than 10 between my weekly 50-70% water changes, and i had just done a water change like 2 days before the angels came in, now im afraid that the others are going to mysteriously die as well but they are all acting normal so i really hope they dont they are really gorgeous, the larger one is still acting more skittish than the smaller ones but still not really that stressed either and i only have the light on, on one side of the tank so they can go to the darker side if they feel more comfortable there
