Kribs are confusing Me

[FishNMusic]

So many questions on kribs.

I visited a friend a friend and his brother which both were keeping kribs. And there kribs seem to swim around the tank But mine always stay in a cave. There kribs have already bread once and the other twice if that does any help and mine once but while i was cleaning out my tank and disturb the nest. The other fish in one tank is some tetras and 4-5 Seveums. In the other tank he has 5 neons. Also My kribs seem dull in color compared to there's. IS there any color enhancer to increase there color or a blend of food. Also what are the condtions for kribs? Would drift wood be good with kribs? Also I heard that for kribs you should put a rock wall around the three edges to have privacy is this a good idea?

Thank you for all your help

I'll answer in order.
1. They probably are breeding again or guarding their "territory".
2. Yours are probably older because their color seems to fade with age.
3. Yes, there's a food called "New Life Spectrum" that is really good.
4. Some what in the higher PH range and harder water.
5. Yes, driftwood is good with kribs.
6. I've never heard of that but it would add a lot of caves for them.
