Re: How would you interpret "minimum aquarium size 60 cm"?
To me 60 cm size would be a 60 * 30 *30 cm tank. However a 50 * 40 * 40 cm tank does contain more water (80 L instead iof 54) which would seam to e bertter. However for territorial fishes, or ones that like to swim length is more important than liters. So yes, sometimes length is sufficient informat...

Re: Long vacation, Fish Survival
Once I changed water, nothing special iI do that more often, and the amount was also normal. But what was not normal was, that an hour later half my headstanders - 3 of the 7 Laemolyta taeniata and 5 of the 9 Abramites hypselonotus started tolling in the tank.

Re: Breeding spoonface whiptaiks?
Groups always do better. In some species males need competition in order to even try.

Re: Cold water catfish like pangasius cats
As far as I know, Pangasius are unlike any other fish. So it will be very hard indeed to find something similar. Free swimming catfish are extremely rare, and most often found in areas where you find lots of catfish. The bottom is their preferred place, but some might leave the bottom, if competitio...

Re: Bare or substrate
The arguments are that a bare bottom is easier to claen, but a saubstrated one reduces stress. I personally think less stress will increase growth, and make the fish hardier against any disease.

Re: Etymology of Mastiglanis? or at least of "glanis"?
As sheat-fish is an unknown word for me, I tried google translater with it,
I got meerval, which is Dutch for catfish
So, apparently sheat-fish must be a synonime for catfish in English. But that does not explain why a sheat-fish, to me that is a fish in or with a sheat, would be a catfish.

No. S multipunctatus comes from Lake Tanganyica, and that is a very large lake, with a constant pH, for eages constant. In other words, fishes from that lake will not be very tolerant in matters of pH, temperature (should be 24 C (~75 F), not the 27 C (80 F) your Heros severum requires) feeding (Her...

This can be explaind, assuming the parents, most likely brother and sister, are both carriers for this color.
