Has anybody found a fast and efficient method of catching tetra or any other lightning fast fish , I remember when I moved house i literally had to take all the water out and scoop them out the puddles in the gravel , thts not an option this time as I don’t want to empty my whole tank to get them , I’m trying to catch 8 2inch fish in 500l Iv caught 2 in 45 mins and had to cancel the sale because I honestly can’t be bothered with the hassle , how do you lot catch fish like this ?
