Anyone care to share if these are sub-species or due to external factors (food, water parameter..)? IMO these tems are the prettiest of all pbassIt will be nice if someone could come out and share with the rest.
soulfly;1544674; said:Get some dark colored substrate. Bare bottom tanks do not go well for bringing out a fish's color potential. The best combo for brining out colors on a fish is light, diet, and substrate. A fish's color can still come out w/a bare bottom tank. But it is more likely to show when a dark substrate is provided. You can also change the diet. Feeders are a horrible source of nutrition for any fish. Try feeding shrimp, krill, silversides, pellets, and other things of that nature.
