i din change water for almost 3weeks.. i jus put it ther and leave.. observe everyday.. the water is like wat i show in previous pic..

im not sure they is how many ther.. cos im using 2ft tank.. kinda hard to locate where they r... i think mayb got 100 or less, now only left 30 gua..

i giv them some frosen dalphia.. but din c them eatin.. so i change it to egg yolk.. it is kinda hard to c them eatin aso.. i seldom giv them food cos i do put plant inside, they may get some food there.. and i afraid it could pollute the water and i dun c they finish the food i giv it to them aso.. recenlty, i get microworm.. hope they do eat it.. they eatin though.. but i still the fry dying.

i have transfer them to small container.. kinda small and put some plant inside.. i feed them inside.. easier to c whether they eat or not.. but later i got to transfer them back to medium tank. not 2ft tank anymore..

should i do some water change like 20%?
