Hey guys, I have a 25 gallon tank. Inside I have a tiger fish ( datnoid ) and 3 tiger barbs. The shop owner that I bougt the tiger fish from suggested that I put black water. And so I am wondering what other fishes can I keep with this set up
yes i would suggest upgrading ASAP and moving your dat to a very large tank.
then you could buy 5 or 6 more tiger barbs and they would look very nice in your 25 as a school.
just my opinion
