he is in a 1 gallon..i change his water frequently..
i have 1 of my girls in a 2 gallon.she is very aggressive and separated her.but she loves it in there.then i have another female in a 20 gallon hex by herself.
my male was in my 10 gallon but the rosy reds in there nipped his fins pretty badly.he has been in the 1 gallon for a while where he was before.once im working i plan on getting another 10 gallon and will divide it for the females and then put the male in the 20 gallon hopefully.
my 10 gallon has 0 ammonia and ntirite as of a test done yesterday,and 5 nitrate...its been like that sicne the end of the cycle the first week of this month.it now houses 4 rosy red minnows,2 mystery snails and 2 otos.i have major algae.the snail have done a great job but there is still plenty to go around. :)
