I have 4 true SAE, which are between 1-2 inches, the 2 Chinese SAE are 2 inches.
I have 120 liter (30 gallon) tank, should I get more? They are rare in my country I might no see some for a year or two not until someone personally orders them.
DO NOT GET MORE
I have had 6 in my 50 gallons for about 9 months now. THEY ARE HUGE. They will only keep growing
