I plan on dedicating a tank specifically for Bumble Bee Gobies. I know they need a good amount of salt, real warm temperature (80-86 F or 28-30 C) and alot of caves in which to stake territories.

I was wondering two things:
what do you suggest for the substrate and if their should be oxygen rich water with alot of movement or very little oxygen and water movement (i've heard they come from slow-flowing estuaries). Thanks!

I have five Bumbles in a 15 gallon with livebearers, krib and gourami. I have the temp. on 25*C like I do for my other tanks and I have 1 TEASPOON of salt per gallon. I think that 25*C is the lower limit for Bumbles, but I didn't want to make it too high for the other fish. 27-28*C would probably be fine for you, and because you just have a tank dedicated to them I would recommend 1TABLESPOON of salt per gallon. I only use one teaspoon because the other fish in the tank might not like higher salt levels, so I had to find a happy medium for all the fish. It's a great idea that you've decided to devote a tank entirely to them - its probably the best way to keep them. Do you know about feeding them? - they can be a bit tricky.

Sorry, forgot to say that you probably shouldn't make the current too strong, I have an Aquaclear Mini on my tank and I think they have a bit of trouble dealing with the direct current, but its not really causing any problems (they tend to stay in the more sheltered parts of the tank). A little bit of current is good for swirling bits of food around - which encourages them to eat. I'm not sure about oxygen levels, but with the higher temp. It wouldn't hurt to have a airstone in there.

People that I know on the web kept theirs in sand. I really don't think it matters much. Gravel is a bit easier, since it's pretty hard to find sand with larger granuals. The particle size of the sand determines whether it will compact easily or not. I have read countless posts on my yahoo groups from people keeping Africans in sand. Also I have my 75 gallon in play sand. I wish LFS stores would stock some kind of non-marine sand to make life easier. Anyways if you use fine grained sand such as play sand don't make the layer very thick, so you can stir it occassionally to prevent compaction. If you can find some sandblasting type sand with larger granuales make sure it has no chemicals added that will endanger your fish.

Thanks alot for the info Sierra and Joyce. So I guess i'll use play sand for my substrate (I wish they sold it at LFS too...oh well to Home Depot it is then ;)).

I did know that BB gobies are hard to feed but that shouldn't be a problem since I raise live brine shrimp for my other fish ;).

Sierra, I never would have thought that an Aquaclear Mini could be so powerful. What would you suggest for a filter then? Maybe a sponge filter?

Well, the AC Mini doesn't exactly create a tornado or anything, but when the gobies try to catch food on the current they get swept along as well. But its not as if they can't swim around normally. I don't think the AC Mini is too much for my tank. How big is your tank? If its less than 15 gallons then you could get away with a large sponge filter or box filter (or maybe several smaller ones). But an AC mini would be fine if you have a 15-20 gallon.

Gobies can be a bit fussy about their food and seem to prefer live food, but you shouldn't have any problems since you have live brine shrimp. I give mine frozen brine and bloodworms and they eat them. They might also try little bits of flake that float past. But they prefer live or frozen. Don't be surprised if they don't want to eat for a few days after you get them.

Joyce, I used coarse gardener's sand in one of my tanks - it have lots of diferent grain sizes all mixed together so it doesn't compact as much but I still have to siphon it regularly to stop it form going black and smelly underneath. I had to wash it really well, too, before I used it. It wasn't the cleanest sand you've ever seen but I guess people who actually want to use it on their gardens wouldn't care!

Yeah, I didn't think the AC Mini caused tidal waves or anything (lol) its just I thought that it didn't have as much force as what you described.

Anyway, the tank I plan to use is a 10 gallon.

I think I have found the perfect filter:
http://www.drsfostersmith.com/product/prod_Display.cfm?siteid=6&pCatId=3954
It is specially designed to prevent fry from being trapped or disturbed and since BB's are so small I figure it would work nice. It would also give the tank a good oxygen supply down there (especially with a temp of 82-86 F). Being as BB's dont produce that much waste and with me changing a good deal of the water weekly, I should have crystal clear water. What do ya' think?

As for the Gardening sand, I keep hearing alot of recommendations from people for this goby tank. All I know is to not buy it with fertilizer in it (duh!). Where can I find it and how much should I use in a 10 gal.? Thanks...;)

Sierra I used a really thin layer of play sand and hardly had to wash it at all. It just looks really "plain" so I mixed it with some Coral shell for my African Rift Lake tank. I have a lip on the bottom of the tank, so you can't tell that I only have about an inch of the sand in some places. My fish seem to be digging it up a bit also, I'm finding tunnels under some of my rocks, so I think they are helping to keep it from compacting.

Your gardening or sandblasting sand might work better for the BB... I don't know if they are diggers so the various grains sizes will probably solve the compaction problem. You can stir things a bit, just be careful not to get too carried away or the sand will fly everywhere and clog up your filters.
