The swordtail seems to be doing well, I see him actually swimming around. I used to never see him like I do the others. He isn't all peppy when I walk by like the others, but he isn't MIA 24/7. Red fish seem to get sick easily...or is that just in my tank? Another red wag showed clamped fins, one of the older fry. How do you fix that, it's the only thing it's doing that is off? My heater is failing, it's on max and the temp of the water is in the 60s. New heater should be here on the 3rd, even though it's been sitting in the state next door for days and easily could of been here sooner. I hate when they do that.
