because you can really tell from those pics, haha! plenty of filtration, water quality is fine. been keeping fish for over 30 yrs. thanks for being concerned.. but actually the glass is all scratched to hell from an alligator that was in that tank over 10 years ago. i currently have Azul, orino, kelberi, mono bass and should have my tems soon. thanks for lookingNice bass! What do you have for stock? Azuls need killer water quality....looks like you need to up those water changes.
