Normal pattern in Hypostomus?

Post by Jorge »

Do you think is this a normal pattern in Hypostomus (I mean, the white lanes in rectangle shapes) or is stress colouration, or belongs to a particular species?

the fish is a wild Hypostomus (at least I think) from Corrientes, Argentina.

All Hypostomus (and many loricariids) exhibit a lighter pattern when under stress. I have never seen that particular sp. however.

Could this be something from the Hypostomus cochliodon group? The "red brunos" show a similar pattern when stressed or on light ground.

Hi Jorge:
Do you have another picture of the fish? The white pattern is because stress, it´s common in hypostomus, and i´m quite sure that the fish is hypostomus commersonii (it could be also h. bourengellii) - not from Corrientes but yes from argentina (90% of the fish form here are fished there, for this reason all appears like from Corrientes).
The important thing is that is H. commersonii the fish prefers coldwater.
Hope that this helps you

Do you have pics of these species to compare?, there are not in the cat-elog and I have not found anything using Google...


I will try to put here another picture if the owner can do it.

Jorge:
i don´t have pics and i don´t have one right now to photograph, but taking a good look, the fish is for sure hypostomus commersonii. The colour in normal conditions is predominant grey with small-medium (depending on the fish) black dots, when are not totally adapted to teh tank, the fish have lot of problems with high temperature (over 24-25ºC), this maybe is the most important thing for this specie that is really really hard.
Here is used and exported for coldwater tanks or ponds
