oh ja antother thing mine look the same but i bought them as ocellaris...
sorry theres a big difference when it comes to temensis and ocellies at birth.... ocellies only have there bars sometimes has a line through them but always fades back to normal... now tems... there stripe stays until it breaks up into there beautiful speckles

so yeah..... and for your mosquito larvae... you need to stop feeding them just live... mix it up.... different selection, see what works for you... as for me... blood worms, krill, or white clouds....
