most bumble bee gobies are raised in freshwater- and chances are if this guy came in on plants- he's been living in freshwater and doesn't require salt in his water.
I have two in my freshwater 29gallon tank.. they are thriving and doing well.
i have looked into pea puffers and 3 would do well in a very heavily planted tank and i think oto's would be ok to because they move fast and are unassuming.
Here is where i decided i was no go on pea puffers- meal time- they are very picky eaters and mostly eat live snails - and i wasn't up...
not all Placo's eat algae - huge misconception in the hobby.
i'm not sure if i'm allowed to offer a youtube but Dustin's fish tanks on youtube did a video on Pleco's and what they eat and i believe yours was one of the species he talked about.
I wouldn't take everyone's word for it here...id do a little research- but a 10 gallon is ideal for an ADF. People get a little overstock crazy around here.
They like a friend with them- they feel safer and you'll see them more.
I have two ADF and a betta in a 5.5 gallon- everyone is happy...
Fish get shipped for longer than 24 hours- in a bag with varying temps..normally without issue- otherwise there would be no fish in fish stores.
IMO i think what you are doing is overkill for the type of fish you have.
i would bag the tetra's, bag the pleco and bag the guppies in two separate...
The two Petco's near me change their betta water one by one by hand-
and bad news- most LFS get their bettas from the same place as Petco/petsmart and they all come in those little bags with the blue water.
The only way to know you have a quality betta is to know your breeder.
do you see signs of fungus or columnaris? If you don't... then your cories may have been wild caught and that is why they aren't doing well in your aquarium.
I had the same exact problem- i got 3 - two died asap, then i got 3 more .. and 3 died... then i got 10 and i had 11 now i'm down to 5...
I wouldn't use sand.. i would use rocks.. the reason being is when they eat they just grab whats in front of them- this will result in them eating lots of sand.
I had two .. a boy and a girl and they mated ALL THE TIME NONE STOP.
the filter the OP has is cartridges and they need to be changed or they fall apart- they also have charcoal in them and if charcoal is old it will release the toxins instead of filter them out of the water. The best thing to do is put a new one in when the old is still in there for a few days...
I dont know if this has been mentioned but keep in mind that a bettas stomach is about the size of it's eye - so it needs very little food and they dont need to eat every day.
I have one betta that doesn't bother with his snail.. i have another betta and it bit both antenas off his snail- so...
Hey there- i LOVE dumbo ear betta's!
If you think about it like this- these little fish have never been in a fish tank .. with lights and gravel and plants and snails.. they been in tubs, bags and jars.
I dont' know about you but if i was all of sudden put into this bigger brighter place...
oh boy to be afraid you're going to get slammed for the wrong substrate is not a good feeling!
i have the same set up in my tank, black gravel, black background and live plants- you'll be really happy with that!
i think if a betta is comfy they don't need to hide. i like the driftwood better because it releases natural tannins in the water which is good for your betta.
i don't know if the coconut does the same but i'm sure if it does someone will swiftly correct me! LOL!
and what?!?!? too many...
