29 Gallon Tank Peacock Gudgeons & Forktail Rainbows

[strobukm]

I've decided that I'd like to keep peacock gudgeons and forktail rainbows (p. furcatus) together in a currently unoccupied 29 gallon tank. The tank has pool filter sand substrate, medium density planting, a pile of dragon rock off to one side and some driftwood. How many of each species should I keep? What temperature would be best? I keep most of my other tanks around 76 F, so that's the temperature I maintain my storage tank of remineralized RO water, but I could make slight adjustments before water changes for this tank if necessary. Any suggestions for other tankmates? I'm fine with keeping just these two species, but would be open to adding others.

Don't know on the rainbows, but should easily be able to do 6-8 of the gudgeons. 76 is plenty fine for them.

Thanks! Should I get 1 female peacock gudgeon per male, or is it better to have multiple females per male?

If you can. Often times they are too young to sex when you get them, though when i bkught out my LFS that day i ended up with 4 females, 3 males. Still got 2-3 month to ID their fry, i am guessing.

Better to err on the side of more female gudgeons rather than more males if possible, but somewhere between a 1:1 or 1:2 M:F ratio should work. 6 to 8 total should be easily doable; I have 8 (3M:5F) in a 20 gal long and they have plenty of room.

You could do similar numbers of forktails. Normally I’ve seen a 1:2 M:F ratio recommended because the males can be rather boisterous, but I’ll let someone with more experience chime in. I only kept a handful once several years ago.

76-78F should be fine for both.

In my 46 gallon planted tank I currently have 6 Peacock gudgeons 1:1 m/f ratio and 2 male Forktail Rainbows with 6 more being shipped so I can school them and keep my bigger male occupied. My larger Forktail when I first added it was going after all my PG’s and trying to pick fights with them around the bottom which are around the same 2” size and the smaller male is super chill and stays at the top. I also have with them Panda Garra’s, Stiphodons, 4 different Endler species which I plan on moving out once I get my 2 Empire Gudgeons being shipped. One recommendation is to have atleast 3 mini caves spread out in your tank in case your Gudgeons breed which mine did after 3 days getting them. It happen to be in one of the centerpiece driftwoods so any fish that get near it the male guarding the eggs chases everyone away. The Forktails I have are super cool with the orange highlights on their fins and deep blue eyes. The Forktail is way more active than my PG’s but they have picked up the pace since I added the Forktails. I’ve added a pic, don’t mind the messy substrate my Panda Garra and Stiphodon made I plan on rescaping a little with new substrate and a seiryu stone retaining wall. I am super happy with both species.
