I have 2 senegalus, 1 is 5" and the other is 9" both were bought at the same time about 2 months ago.. They were both 4".. They were fed on beef heart.. I now want to get them on pellets.. They have'nt eaten in the past 2 days.. I've been throwing pellets in front of them, they just smell it nd move on.. Sinking pellets r not availabe here.. I've been trying to feed them AZOO's Arowana sticks.. Any ideas on how to get them to eat pellets ???
