I bought 3 clown loaches 2 weeks ago. Two loaches are 8 inches and one is 5 1/2 inches. The two large ones came from one tank and the smaller one I purchased from and different tank. The stores PH was 7.8 and I acclimated them very slowly with a drip to a tank 6.5 PH. They seemed fine and were not breathing heavy. But the larger two are not eating. So I slowly brought the PH up to 7.0 and they are still not eating. I tried Frozen blood worms,Romain Lettuce, and Zucchini. Temp---is at 78 degrees PH----at 7.0 all other readings are good. HELP What else can I do ??? The only other thing I thought of is to try PraziPro or Metronidazole. Any suggestions I will really appreciate---------
