Don't worry I keep up with them all, if the bottom of the tank looks dirty it's just scratched up from being a 12 year old setup, the only fish not in here still is the rtc/tsn hybrid
Like i said above if your talking about the bottom of the glass its all scratched up from being a 12 year old setup so there is nothing i can do about that for now, as for the decos all of them look clean to me other than some particles flying around from food after i just fed them in the video. Positive responses are nice too just saying
