i had my betta Rambo for aprox. a year now and i have to say he is doing fine- he swims all over, eats well, and poos well.
i have him in a 1gallon tank with and O2 supply pump (but i dont usally run it cuz i keep reading bettas like still, quiet enviorment) & and i feed rambo frozen bloodworms, frozen brineshrimp, & mashed peas- each on diffent days
BUT ive been reading a lot about "bubble nests" lately-wich im not familiar with:
-what are they
-what do they mean
-rambo doesnt have one, does that mean hes not healthy/happy
