Hi, I have an 80L tank. It contains 5 neon and 3 black neon tetras, 2 dalmation mollies, 3 ottos and did have 4 guppies. These have lived together for 4 months without any issue. However, the water went pea green. I regularly test the water conditions and all was well for ammonia, nitrites, nitrates and ph as well as temperature.
I diagnosed that I was leaving the light on too long and have now put this on a timer. I read up on how blacking out the tank for 72 hours would get rid of the pea soup and this is what I did. I also accepted the advice that the fish would not need feeding during this time, however I did feed them after the 2nd day (the tank was still blacked out at this time). When the covers were removed I was one guppy down, no sign anywhere in the tank.
The next night I was another guppy down again no real sign of him (all fish are males) other than one guppy was looking to be chewing on something white which looked suspiciously like fish flesh! Last night the last two guppies have gone missing. Nothing of them remains.
The tank is covered and so they are not jumping out anywhere, I have covers over the onboard filter housings so they are not in there either.
So, who dunnit!! and more importantly, what if anything can I do about it? I would like to replace the guppies since they added extra colour to the tank and appeared so happy in there!
One of the mollies is the boss and especially at feeding time will chase the other very aggressively but I have never seen him bother with any other fish who are feeding right next to him.
