29 Gallon Stocking Help
So I have a 29 gallon tank that has been established for approximately 8 months. The current stock is 8 Harlequin Rasboras and 1 German Ram. I was looking for some ideas on additional stock. Options are somewhat limited around my area. I had a school of 6 cories in there but they slowly died off with no real explanation. So any ideas?

Welcome to the forum!

First, we would need to know your water parameters (hardness, pH, temperature) and perhaps a bit about the setup, (filtration, plants lighting)... and maybe what the cory die off symptoms were.

I agree. After more information on the setup is given, we can properly recommend some fish.

Right I suppose I should have known better and posted some of this stuff.
ph-7.6 Ammonia-0 Nitrites-0 Nitrates- 10ish Temp-76F
The tank has a sand substrate with 3 small wisteria (I think) but otherwise moderately planted with fake plants. I run an Aquaclear70 filter. And as for the's a bit of a mystery. They had no noticeable symptoms, they would all appear healthy and active and then I'd wake up the next day and one would be dead with no signs of illness or foul play. They died off one at a time over the course of about 3 months.

The most obvious answer is to bump up the rasbora to an impressive sized shoal for your tank size, you could top them off to 15.

With limited options, Corys are the best next group but the history...

Quick answer anyway.

Corys can be difficult, but I would be interested in knowing the species you had. Some are more-so than others.

As for other fish, I would normally suggest increasing the rasbora, but here I would not. Eight is a decent number in a 29g, and having another species or two, which probably will mean groups of each, will provide more interest. Of the three frequently-seen Trigonostigma species, T. heteromorpha (the Harlequin) is the largest and tends to do OK with not as many as the other two species are better at.

Depending, corys might be good, a group of 6-7 [might have suggestions when I know which species you had]. Whiptail Catfish or the Red Lizard Whiptail Catfish are hardy and rather more interesting for a substrate fish, while not getting large--just make sure it is the Rineloricaria species in our profiles, there are some similar species that get large and may appear under the same common name which is misleading.

For other upper fish to match the rasbora, some of the quieter tetra can work. Pristella maxillaris, Lemon Tetra, Black Phantom Tetra, Black Neon Tetra come to mind for being different colouration.

The cories I had were the peppered cory (C. paleatus). I wouldn't mind another school of cories as they were always active and highly social among one another but the fact that I could never determine what killed them off last time has me weary. The whiptail catfish looks cool but unfortunately I've never seen one at any of my local stores.

I was looking as bottom dwellers and hadn't got to the catfish other than to consider one of the cory species. I might consider the whiptails instead. The difference between the two whiptails (besides the coloration) is the temperature range. The Red lizard is up to 82F whereas the "standard" is only up to 77F.... oh and the diet is slightly different.

Finding the lizard variety might be tricky, just got to talk the store manager into really liking them.
