To answer your question piranha 45 I have changed water once every two weeks and I due a 20 % water change. Wen it comes time to clean the rocks I do my best but try not to take all the dirt because I believe they kinda need some bacteria going on but I could be wrong. Well I guess you guys are right but I need to get good deal wen it comes to sell my smaller tanks. I have 3 29 gallons and 6 ten gallons but they all full of other tropical fishes. I original want to get a 100 gallon tank. But I think I just minus well build one on my own because I dont agree with the prices of tanks and some type of cichlids now in days.
However I just cant let go of my oscars. I got them wen they were very tiny and almost dying from Walmart. I got them home and I took good care of them till this present day, and just the imagination that I have to give them away hurts my feelings.
