I was reading the fish cycling sticky and i am using the fish cycle method. some of you said to make sure to change the water every few days and so i did a 40% water change after 4 days. now the fish are acting all weird (tiger barbs) and they keep going behind the plant and near the heater. i had 6 and now i have 5.. the last one i found dead behind the plant and it looks like that's where all of them like to go before they die. =( what can i do to save them?
ps - should i get a gravel vac for a 10g tank? and how much do they go for?
