I was wondering because I am thinking of putting my fish with loaches in a tank with no substrate. 

Thank you for your prompt reply. That answered my question completely.Steve_89;2574795; said:It will be fine.
It is very rare to see a jardini with drop eye.
What you could do is put something on the outside of the base of the tank. There was a thread on here arguing whether fish could see their reflections in bare bottom tanks.
Some hobbyists believe they can while others are not so sure. I just took the safe option on my asian aro tank and stuck black cardboard onto the base of the tank![]()

i totally agree. its gotta be the genetics, and overall care can add in to. IMO. highly fatty foods, make more drop eye. but, as silvers age, it happens. no matter what.Cypher;2577003; said:This issue has been in debate for YEARS. Honestly, I think it is pure genetic more than anything else. Ive seen asian arowanas getting drop eye with and without substrate. IMO, its all about the genes.
