i have 7 danios in my 15 gallon tank . I have mentioned earlier in my previous post. I am very new to fishkeeping. So when i bought them home , i saw 3 out of 7 are too tiny ..they dont get harrased or bullied but they are so small ...like 1/3 rd of the big danios. Its been a week havent seen any growth so far. Will they grow? or thats it?
