How many Rose Line Sharks in 100 gal tank?
 
Please advise!

I have 12 gorgeous Puntius denisonii (aka Rose Line Shark, Red Line Torpedo Barb, Bleeding Eye, etc. etc.) happily quarantining in a 20 gallon tank. They are about 3.5 cm long (aprox. 1.5 inches). Soon they will be moved to my 100 gallon system (comprised of a 65 gallon display tank and a 35 gallon filter/sump - massively over-filtered and moderately planted.)

How many of these beauties can I realistically keep in my 100 gallon system:
if I keep only them in the tank and no others;
if I keep only them in the tank with 3 botia kobutai (2.5 inches each) and 3 botia histrionica (3.5 inches each);
if I keep them, all six botias, and four rainbow fish (full grown size 3 inches each);
if I keep them, all six botias, the four rainbows, two 3" blue gouramis and some green tiger barbs as well????

I suspect the answers range from all in the first scenario, to none in the last, but I am anxious to get the opinion of other folks in the hobby.

THANKS FOR YOUR HELP!

I think you can keep the group of 12 for quite some time, but long term you will need a bigger tank. These guys grow to over 6'' in length, so a 65 gallon display is really at the bare minimum of tank size that you would want to consider.

No changes. The area of the water column occupied by these fish has no impact on the denisonii.

What type of rainbow? Their size ranges from 2'' to 12'', depending on species.

This combination will work fine for now, but within 3 to 6 months as the denisonii grow you will have to eliminate most all of the additional fish listed here.
