I am going away for a long weakend. I have 33 Bettas in all. Most of them have circulation, but there are some that i keep in jars that i show. Is there anyone that knows enough to tell me how to feed the one's in the jar for about 4 days? The betta's with filter and air , I just feed them the automatic feeder blocks, but you halfto have circulation for those. Can anyone help me out.
