Re: Featherfin & Petricola temperature?
They both come from the same water. Lake Tanganyica, so yes it should be the same. I myself don't keep fishes from that lake, so I cannot tell you. However, keeping Lake Tanganyica fishes together with tetras from rivers wille not be a good idea - the tetrs will prefer softer water. I would reshuffl...

Re: Raphael's are very fat?
My Platydoras did come out when I fed the other fishes, always during the day. They ate anything I fed.
I always thought a happy, healthy Platydoras is fat.
I've kept them for 27 years or so, but one day an illness killed both of them, together with two Pterogoblichthys gibbiceps of 23 years old

The group Teleostei is of a higher level then catfish, and thus all catfish are teleosts

That would be a good incicator, but I would also look the wood pieces over after a few weeks. For dark, rotten pieces. However, as the wood is intended to be eaten, your fish will love these rotten pieces. After all, they live from the rotting bacteria.

Rain is the same everywhere - very soft and lightly acidic. If it falls on a swamp, or a rinforrest, it will not come into contact with minerals, and remain soft. It can get very acidic. If it falls on other places, it will contact minerals and harden rather rapidly. However this will take time. The...

These are best kept in a group, and personally I never saw 2 doing fine - and 2 is the maximum I would put in a 9 US gallon = 35 liter tank
Shrimps or snails, that's it. I do have quite a few good algae eating snails.

That can happen because you changed it, or by good plant growth. But that would require more than a year I'm afraid
