Maybe something like this?
You don't leave the trapped fish in there, put them in something for holding. An endler can survive in a tub or bucket with just an airstone. They are a very hardy fish.A few days would kill the fish. There is no flow inside the trap, and that dead spot would kill everything in it.
How about a larger net? Lay the net on the bottom with the handle close to the top. During feeding, just grab the handle and bring the net upwards. I have an easier time netting fish from the bottom going upwards.I have a 10 gallon planted that i want to remove the endlers i have in there, a lot of little ones with adults. any tips on trapping them in bulk rather than chasing them around the tank with a net?
thanks
