I've had baby bowfin in the past and lost them in a matter of weeks both times i kept them. recently i ordered 3 more all 2.5-3". they were doing great for 3 weeks and then 1 by 1 they all died. i started out feeding them small pieces of tilapia.and small rosey reds. treated the tank with prazipro. for the 1st week. did a water change, put carbon back in the filter and the next day 1 was dead.so i removed the carbon and retreated with prazipro.2 weekslater , carbon, waterchange , both remaining stopped eating , 1 died the following day and a day later the other died? what was i doing wrong?....pH was 7.4-7.6 temp 78F, 0 ammonia, 0 nitrite, +- 20ppm nitrate.oh, and if it matters , when i pulled each one from the tank they were REALLY slimey. i mean EXCESS mucous.am i missing something?
