Given the comment in the profile of the Red Tailed Shark about being the only substrate fish and its annoyance with fish with vertical stripes, I would not combine it with Botia striata. And it could go both ways, as this loach can be domineering itself.
Do you think the puffers would fare better than the RTS in the Rainbow tank? Or should I just try the puffers and RTS in the 35? That's kind of how I'm leaning. They're all small fish right now.
Assuming the puffer is Colomesus asellus [another species is very similar, C. psittacus], it is said to be OK in a community but not with sedate long-finned fish as it may nip. So I would try it with the Shark.
Thanks Byron, that's how I was leaning. I'll keep a sharp eye on them. In the 10 gallon they haven't shown aggression to each other at all (they are aggressive eaters) and they have never used any of the three hiding spots I provided (I set it up expecting dwarf puffers, which have a different personality)
I'm going to have to change the substrate in that tank. The 10 gallon looked natural but the RTS tank has circus substrate. I'm going to go with that natural beige mix. We don't have that in any tanks. Our last two we went black.
I'll put some more plants in the RTS tank to break up line of site some more. The puffers seem to like swimming around the plants.
I have a rainbow shake which I hear to have the same mentality as a rts in a 29 gal tank, the only thing I recommend is that he has a cave of some sort, I had mine for a while be for I got him a hiding place and now he seems to be much better, he chases some fish around some time and then will return to his cave.
He hides in a cave created from one piece of driftwood leaning on another. There is an actual cave in the tank, but he chose the driftwood cave early on and that is definitely his territory. If the puffers try to move in on that area they will get chased for sure.
They only get to 1" so they may be too small to be with some cichlids. Also, I don't know if the water requirements are the same. But I don't know enough about cichlids to say one way or the other. I do think dwarf puffers are ideally kept in a species tank, with just dwarf puffers. Which is why I set up the 10 gallon just for them.
