Water Boxes Update - Vinegar Eels

Got home a little late tonight feeling a little anxious about the new fry but when I looked in the tank they where flitting around and looked fine. Still pretty tiny but they all seem to have something in their bellies. I squirted in some vinegar eels and got a few walter worms from the box I started last night also.
I have tried both vinegar eels and microworms as tiny fry food in the past and much prefer vinegar eels. They have a few big positive attributes as far as I ma concerned - They don’t stink - even when old. They live in the water column of the tank for about a day - (hard to really tell) They do not sink to the bottom and die right away, polluting the tank on the way like microworms can.
I keep a total of 4 bottles of vinegar eels - 2 are florence flasks that I use to feed from and two are old wine bottles I use for a ready backup stock. I had poured off a lot of one of those bottles to distribute at the meeting last night so when I got back I freshened all 4 bottles by pouring off the liquid to a bowl, dumping the old apple slices I have in all the bottles. I then added more apple to each and some of the old liquid plus some 50% water and 50% apple cider vinegar solution. The wine bottles are filled almost to the top and stoppered with bits of old filter sponge washed and cut to size. I fill the florence flasks with apple/ old liquid (with worms) and new vinegar solution to the bottom of the neck I then insert cylinder plugs of old filter sponge. I push it down to the bottom of the neck and fill above it with plain water. The worms go through the sponge to get to the fresh water above and gather there. It is then really easy to use a dropper to get them off and squirt them straight into the fry tank! I learned this trick from this livefood culture Site.
The wine bottles with the stock just sit in the back of my shelf for club meetings or a sudden need for a gizzilion worms….
