hey there everyone i have some questions.i'm new to fishkeeping and i have a 10 gallon tank..i believe it is still cycling and i have 4 danios in it with a pleco..the tank has been cycling for about 2 weeks now and the ammonia is at .25....now my 2 zebra danios are looking pale and swimming at the bottom of the tank..they swim frantically sometimes and this isnt the same behaviour as when i first put them in..does anyone have any suggestions?
