So you say a 30 gallon is ok for life Anne? Just wondering. Would a 20 gallon long be fine? Cause I have mine in that size but I am upgrading to a 75 gallon.
She's right. Your typical polypterus senegalus from the pet store comes from stock that has been farmed so long that they don't reach their full potential sizes, and you'll see various body shapes and what not, but mainly shorter length.
There is a difference however between an active bichir, and a bichir that is annoyed by it's confined space and is swimming against the glass.
