Well I have progressed in my initial foray into aquaculture from a betta bowl of ca. 1.5 gallons, to a 4 gallon Finnex tank. Moving up in the World! But now I have to decide what species of fish to put in the 4 gallon - what I'd call a small tank or "nano".
This 4 gallon has a 13 watt light and a filter - both new add-ons after having only a bowl. It will also have some small plants: probably some Echinodorus tennellus
or saggitarias, and other small plants. No problem with the plants selection. There won't be room for too many!
But now that it has come down to it, what fish? I think that I want to have just one species of fish, and if possible a small "school" (after one betta I'd like to see some "movement"). To give you some idea of what I have already thought of, and, for now, discarded:
~ WCMMs (White Cloud Mountain Minnows) - because they are real swimmers and the tank would be too small for them,
~ Paradise Fish - because I was told the male only colors up with a female and I don't think a 4 gal. would be big enough to allow her to get away from his attentions, and besides, I don't want one fish, I want to see some action after having only one betta,
~ Guppies - if the males didn't wind up trying to take on each other and they weren't so proflic with females in the tank,
~ Neon tetras - maybe, maybe. Some say they are a lead pipe cinch - others that they are problematic (this is going to be my first true fish tank so I need some wiggle room for mistakes), but it they really are as easy as some say...maybe!
~ Colisa lalia
- maybe same problem as with the aforementioned Macropodus
? i.e. not roomy enough for a pair and just a male would be cruel and unusual punishment
even if She weren't needed to color him up (but my! aren't they great looking, some of the more colorful clones!?)
~ And lastly, but not leastly, Killifish
. I still haven't eliminated them. They seem to have some of the attributes I am looking for: a) small (necessary in a 4 gallon), b) colorful (some are really colorful!) , c) easy to care for (I think), d) would enjoy the lack of water movement I plan on having.
If Killifish, how common are they in the trade? I don't recall seeing any at PetSmart. I can't do mail order now with Winter holding sway here in the frozen Inland Northwest.
So which fish for a nano?
