Quarantine Tank Size and Filter for Multiple Species

[smoosh]

Hi everyone.
I'm planning to set up a quarantine tank for some new additions, and I could use your expertise. I'm planning to quarantine the following fish for 2-4 weeks before introducing them to my main tank:

• 10 Neon Tetras
• 4 Boesmani Rainbows
• 4 Dwarf Neon Rainbows
• 6 Otocinclus

What would be an appropriate tank size and filter setup for these fish during their quarantine period? I want to ensure they have the best conditions during the quarantine period.
Thanks in advance.

The rainbows won't do well with the neon tetras & the otocinclus. The rainbows need PH of 7-8 and higher temps (80 - 86F). The Neons and otos do better with lower ph and temps in the low to mid 70s.

If you keep in the same tank, but you'd have to compromise the best conditions for one or both types of fish.

Edit- one other note: both neons and otos are best introduced to well seasoned tanks- at least 6 months old. Neons need water with low bacteria and otos need lots of biofilm and algae to munch on.
