How about a pair of rainbow cichlids, I have a pair in a 29 and they’re very fun to watch. Big cichlid personality in a small package. ( I was rescaping when I took this)I am looking for 1-2 fish that can live in my 29-gallon for its whole life. They don't need to be the same species.
Please note I said 1 or 2, I'm not looking for a school. They shouldn't be teeny little fish, looking for something good sized.
Needs to be relatively easy to keep, easy to find, and is less than $20.
The filter is an Aquaclear 70 so there will be decent flow.
NO SUBSTRATE and minimal/no decorations.
Some things I have thought of (not sure if all are suitable in my tank):
Option 1: One Firemouth Cichlid
Option 2: One Fancy Goldfish
Option 3: One Peacock Spiny Eel
Option 4: One Convict Cichlid
Any other options you can think of? Thanks
Shell dweller cichlids would also be very cool in a 29
