I was unsure wether it would be better to have some lonely and stressed hastatus or some mutt cories. Thank you for your help!
I agree that this is the main issue/problem. Give the pair a chance to spawn, but I would not let them be alone for too long.
So my plan going forward is to try to encourage the hastatus to breed in my 10 gallon. It currently has sand, lots of plants, some driftwood. I’m going to order some Indian almond leaves, cholla wood, alder cones, maybe some anubias. Should I get a new piece of driftwood? The one I currently have is a manzanita branch, been in my aquarium since April. I didn’t know if a newer piece would have any kinds of benefits?
This sounds a good plan. Old wood is preferable to new here, because it is going to have infusoria on it. At the same time a new piece added would have tannins which are more beneficial than not, but of the two I would go with the older wood if a choice has to be made.
Rather than ask Ian directly, I posted the question on his site, thinking that Ian is in the UK and the NA members might have more up-to-date info on availability. And I seem to have guessed correctly. One US member advised that someone found C. hastatus in a Petco somewhere in Washington state. Others noted that we are getting into the collection period in South America, and should see this species in the next few months. You may have luck with The Wet Spot then.
