Hi everyone, newbie here
Seeking advice on how to stock my 55-gal
tank. Right now I have 3 damsels that the LFS
sold me to get started (I had live sand and the bottled bacteria so my ammonia never got too high for them, they didn't suffer). Two are dominos and one is a yellowtail. I heard the yellowtails are not as aggressive and this one doesn't seem to be that bad so I thought about keeping him and taking the dominos back since they are bullies. Here are some fish I like that I think would be good but I know I have to eliminate a few choices to not be overstocked, maybe you can tell me if any are less desirable to help me eliminate.
Kaudern's cardinal (probably 2)
firefish or bicolor dottyback
coral beauty angel
six line wrasse
I'd also like about 5 snails and 5 hermitcrabs and a featherduster someday (when to add these guys?)
Please give me your opinions on compatibility and the correct order to add them. I have a 20-gal
QT I will be using for each addition for 4-6 weeks. How many do you think I should add at once? I heard only one at a time, but I also heard 2-3 if they are small fish.
Thanks in advance for your advice!
