My girlfriend and I have a 35 gallon tank with 2 GT's and there are 2 catfish in there as well. The GT's are about 5 and 3 inches long, and both the catfish are around 5. We are trying to find a new home for the catfish because we know that tank is not big enough for them. The GT's are awefully skiddish, so I wanted to get some Tiger barbs or something like that. Do you have any suggestions for type of fish to put with them? and How many would work in this 35 Gallon set up?
