Many already know what this issue was before opening the thread.....
My wife bought me a couple of these tiny things about 9 months ago when I was regaining interest in planted tanks. I explained that they would be too big for the 3ft tank when I arrived home from work, but being a surprise what can you really do?
At the same time I had bought a nice batch of 20 cherry shrimp to be the main feature, which over months became around 50 with the dense planting. Really lovely bright red and very active.
And then we come back to my wife's "lovely" sharks, which by now have grown to around 4inches long and have bunched their way through every shrimp in the tank. .
I had noticed the numbers going down, but thought they had hidden again under the wood and in the dense plants.
So to anybody who thinks "I'll be fine with these for a year or so before issues"..... Think again, they grow surprisingly quickly.
