i've lost some fish (to old age), in the past few months and think i am ready to add some new fish into my 30 gallon aquarium to replace them. currently i have the following fish in the 30 gallon,
1 red tail shark
1 roseline danio
3 leopard danios
2 zebra danios
1 tiger barb (and yes i know i should have more than 1, but i am trying not to have these anymore...so as they have slowly died I have not replaced them.)
the shark is a little on the nippy side, so i don't want to put anything in there he will really be tempted to go for.
any ideas?? i had a gourami in there years ago, and I really liked that, but it was before i got the shark, so i don't know if he would be compatible or not.
also- in a 10 gallon, i've got one male cherry barb, three habrosus cories, and 6 harlequin rasboras. can i add to this, or should i just leave it be, since i've not had any issues? I don't want to push the tanks limits. (tank has been up and running three years, and not a single fish death! woohoo!)
in general i take good care of all my aquariums, regular water changes, adequate filtration, test water regularly, and I feed the fish a varied and balanced diet. but i still respect that every tank has its limits. so if anyone thinks I am at a maximum load of fish in either tank, i would rather not risk stressing out the environment. i want to add a few more, but not at the expensive of my current pets.
