OnlyGenusCaps Posted November 19, 2021 Share Posted November 19, 2021 I've got some pupfish in a 75. Yesterday there were 8, today, 7. One of the males was thin and on his way out. I attributed this to the ratio being 5 males to 3 females, and he was the smallest, thus being bullied. Or this is what I thought. Today I noticed another male flashing on driftwood and the sides of the tank. At first I thought he might be fighting his reflection, but not on the driftwood and gravel obviously. So, now I'm at a bit of a loss. Do I medicate the 75? If so, toss it all in, i.e. MedTrio? I know flashing can be caused by a lot of things so normally I'd wait and watch a bit. But... I just lost another fish in the tank I am headed out of town for a few days starting this weekend these fish are extremely rare not just in the hobby but nearly extinct, so I feel the need to help keep them going I'd sure like to get your take @Colu, if you don't mind. Oh right, and water parameters (according to the breeder I got them from, I'm pretty spot on for conditions): Ammonia/Nitrite/Nitrate = 0/0/<5 pH = 7.8 Hardness = real hard Temp = 25.5C 1 Link to comment Share on other sites More sharing options...
