New tank, New fish

[Zack33]

Hey everyone,

So I am setting up yet another tank, this time it is a 20 gallon Long tank. I am going to be going with a fairly open aquascape with hopefully only one rock island which will be right infront of the overflow in the middle of the tank.

What does everyone think of this list of fish:

- 1 algae blenny
- 1 Purple firefish
- 2 or 3 Cardinal Fish (species not yet decided suggestions?)
- 1 sand sifting goby (again species not yet decided, perhaps a goby pistol shrimp combo)


I have heard bad things about mixing blennies, firefish, and gobies together. So I could use some input on this stock list (I was going for a bit more of a peaceful tank than my larger tanks).


Thank you in advance,
Zack

Looks like a nice combo to me. For the cardinals, I would go with a pair of bangaiis. There are a couple pairs for sale on Diver's Den.

It all depends on the type of blenny and type of goby. I've got a tail spot blenny mixed in with a fire fish, 3 masked gobies, a rainsford, a neon, a shrimp goby with tiger shrimp (can't remember the species off the top of my head) and 3 green banded gobies and everyone get's along just fine. I wouldn't put one of the larger blennies in with small gobies. But if you go with a tail spot or a barnacle blenny or something along those lines you should be fine with small gobies.

My tailspot is fine w/ my shrimp goby & he was in the tank first. Add the firefish first, they are the shyest of the bunch & will already have a territory when all the neighbors move in down the road.

Id say too many fish for a 20 gallon

It'd be ok if he goes with smaller species. A small blenny, some red stripe or red spot cardinals, a firefish and a small shrimp goby. The firefish would be the largest thing in the tank. Other than the firefish, none of those fish get over about 2 to 2 1/2 inches. Those would be fine in a 20 gallon, especially since it's a 20 long.

If he went with the larger species, then yes, that would be too much for a 20 gallon.

If you really want to go small, you can stock with just gobies. Plenty to choose from that inhabit all levels of the tank. Just stay away from eviota's as they have a lifespan of anywhere from about 6 months to 2 years depending on the species. Trimma's are a little better, but most of the other species seem to have longer lifespans.

Thanks for the responses everyone! I will update once the tank is cycled, finally hoping to get rock and the pumps going in it this weekend. Potentially, I will do a build thread once it gets going.
