Fishes:
1 Gold Gourami (Mid size)
6 Black Skirt Tetra (fully grown)
6 Serpae Tetra.
There used to be 8 Serpae tetras but the last time I went on a vacation for 4 days, 2 were missing. Nothing was found! I guess the rest of the fishes ate them. I don't want anything like that to happen to any more of my fishes. So I bought weekend food block (Toyo brand) from the nearby LFS.
Will the fish be fine if I put 3-4 blocks in the tank? Or the blocks will dissolve too soon?
Additional Info:
2 Sponge filters.
100W heater set at 26c.
Help is deeply appreciated
