I am getting a 55 gallon tank soon and i am looking to get some help on the things i will need. i already have a 20 gallon thats doing fine but isn't really all that exciting. i'm trying to make the 55 my really good tank. the one i can sink some money into (no pun intended). i plan on getting the marineland c360 for my filter. i am thinking of getting a external inline heater but i'm not sure if i should just stick with the normal submersible heater. i haven't decided whether i am going to have plants or not so i was going to just put in a substrate that would let me grow them if i want to in the future. if i do i am going to get a co2 system but i don't know what i should get. my questions are: what else do i need?, where can i get the best deals online?, and what kind of lighting should i get? any help will be appreciated. thanks.
And btw, if your getting a clown loach.. you need at least 2-3 they do terrible as a solo fish.
