So life has been peaceful in my 55g, for ~10months. It was cycled about 15months ago with 5 little Rasbora Heteromorpha Danio no bigger than 1", and 5 neons. After 3weeks, I added 1 Rainbow Shark
, 3redline sharks, a Leporinus fasciatus
, and a ghost knife. The ghost knief didnt last long. The redlines faught eachother until their was only 1 left. And, other than some algea, all has been well.
Last week, 10days ago, one of the neons was swimming funny, it looked like fin rot, but I didnt unserstand how that would have happened. None the less, I scooped him out and dropped him in the aquitic frog tank. (I know, the food chain is very heartless.) I then began to survey each of the other individuals, and everyone looked fine. BUT.... There was only 3 neons. So, i picked up each decoration checked the filter. There was no trace of the missing fish.
Today, I drop in a couple of treats they got for Christmas, and the black and silver fellas go to town as they normally do. The remaining neons joined in, the redline and Leporinus fasciatus
hung out in the mid waiting for their pieces to fall, and the Rainbow Shark
was on the back wall eating allgea. Several hours later, I walk by and there is 2 dead fish!!!!!!! 1 neon, in the mid towards the back wall and the Rainbow Shark
on the opposite end of where he was working earlier, towards the front. Both with all fins fine, head and back bone in tack, but with their stomachs ate out.
The Leporinus fasciatus
and redline shark have both more than trippeled in size since I got them. Now are both about 5". They are my main suspects. But, I have not witnessed either to be so aggressive. WHO IS THE MURDER????
