Tank set-ups: 1. African cichlid aquarium All of these species are relatively friendly and have different behaviours that will reduce stress between different pairs. These species prefer a well planted aquarium and leave your plants alone so that you can use all sorts of plants. They also require hiding and spawning places. Kribs spawn in caves which can be created using roots, rocks and flowerpots. A. Thomasi spawns on flat surfaces such as rocks. You will have to leave free areas without plants and rocks to create swimming space and allow you to see your fish more often. Use fine sand as this promotes spawning of Egyptian mouth-brooders. If you just keep aquarium clean and your fish well fed they will thrive and spawn in this aquarium. If you find your aquarium a little empty you can add some small schooling fish such as tetras to upper water levels.

2. Central American aquarium The species in this set-up are more aggressive, which explains why I only recommend keeping two species in this tank. Both species lay their eggs on rocks so caves aren't that necessary, but I would still recommended that you create a few as hiding places as these species can be quite aggressive. This is especially true when they are spawning and caring for their young. A sajica usually leaves your plants alone, but convicts often eat plants, so I recommend using more hardy plants such as sword plants, anubias and Java ferns if you want to use plants. Whether to keep plants or not is completely up to aquarist. The cichlids will thrive with or without plants as long as you provide a few hiding places. Both species are very easy to breed and it is almost impossible to keep convicts from spawning. It can be very hard to find new homes for fry, so I recommend letting parents keep their young and see if any survive. In this aquarium some usually will.

3. Amazon aquarium As I said earlier, it is preferable for this aquarium to be at least 50 gallons since these fish get a little bigger. Angelfish shouldn't be kept in aquariums that are less than 50 cm/ 20 inches high. These species are still easy to care for but require a little more from their keeper to spawn. The aquarium should be well planted with free areas for fish to swim in. Use large sword plants or cryptocoryne species to give angels what they need to spawn. The other species requires roots or rocks to spawn on. Caves are not necessary but preferable, especially for A. curviceps. If you find this aquarium a little empty you might add some free-swimming schooling fish to aquarium. Never use neon tetras with angelfish, as angelfish like to eat them. The same is true for a number of other small tetras. If you keep water clean and fish well fed they will thrive and with a little bit of luck, spawn.

Final words I have given just a few suggestions for possible cichlid aquariums (there are a lot more) and when you get a little more experience with cichlids possibilities are countless. Cichlids are very interesting and often beautiful fishes and many of them are quite simple to keep. These are only a few of reasons behind their popularity. Try them, you won't regret it!

In aquariums gars are quite demanding and require a lot of space and clean water. I recommend you to use as big a tank as you can for your gar, and I wouldn't recommend keeping gars in an aquarium smaller than 200 Gallon/720 L. And that should be considered a minimum; a 400 gallon/1400 L tank is preferable.

The tank should be decorated in accordance with gar behaviour. Gars are ambush predators, and as such they appreciate hiding places from where they can stalk their prey. This is however not essential. They are very friendly towards fish that are too big to be eaten. In wild gars often live in loose schools and if you have space you may successfully keep several gars together, in fact I would recommend this.

Gars can be kept with most fishes that are too big to be considered food and not too aggressive. However, gars should never live with plecos. Plecos sometimes suck on gars and cause infections, and since gars are very sensitive to most medicines these infections may be very hard to treat.

Regarding water, most important thing is keeping water clean and well circulated. Gars accept most pH or hardness levels. Temperature can range from 60 to 90 degrees Fahrenheit (16 - 30 degrees Celsius). Gars breathe air and should be left with a few inches of space at top of tank to allow them to breathe atmospheric air.

Gars usually accept most kinds of living prey that are large enough. Feeders such as goldfish provide a good base for their diet but should never be only thing they are fed, since this would not provide gars with all necessary nutrition. Their diet should be diverse, and this can be achieved by also feeding minnows, shrimps etc. It is also possible to train gars to accept frozen foods and pellets.

Gars cannot be sexed externally. They have occasionally been breed in aquariums but are more frequently bred in ponds or are wild caught.
