That's great.

What type of lid will be used? I've read enclosure should be humid.

Most cichlid species do that. Territorial behavior or spawning. That's probably the tank boss cichlids also establish rank.

If the swordtail and guppies are healthy and eating well I personally would try another lfs. Quarantine before adding them to your main aquarium.

Do you have any other fish in the aquarium?

Are you buying the Molly's from the same lfs?

It's up to you. If you keep them in the mesh bag don't allow bag to get clogged with waste also suggest maintaining prefilter during each water change. I would not rinse the prefilter under tap water because beneficial bacteria will cultivate on it. It can take a cycle up to 6-8 weeks. Everyone experience different full cycle times. I would do extra smaller water changes and test weekly until water parameters stabilize.

What size aquarium are the EBA in? I ask that because if aquarium is a 20gal or smaller it's going to be rough for other inhabitants.. I personally suggest letting the parents rear the fry but be aware they may eat the eggs because it's their first spawn. Now is the time to figure out what you want to feed the fry when they become free-swimming. Most start with baby brine shrimp which is one of the most nutritional first foods for most baby fish. Some cichlid fry will eat microorganisms from plants off sponge filters also pulverized flake food or pellets may be accepted. What other fish do you have in the aquarium? Also like to add water quality is important so don't overfeed and more water changes should be done.

I like your plan. Whatever is easier for you especially removing the fry.

I suggest go pick up cheap tote. I think that's too high and risky.

Definitely agree.

If you want lower nitrate you can feed less easy green.

If plants look good and growing then keep doing what your doing. @brayden malone

At the time I was feeding the brand San Francisco Bay squid cubes.

I don't know about the smell but had a saltwater Snowflake Moray that went nuts on squid 😆

I suggest check your water parameters asap. @Loc Tran

This is crucial for keeping a Oscar from getting infected from HITH. Great advice given.

3/4 plywood is available also at most diy stores. I agree with staining the wood.

I suggest netting or using a hose and siphon the snails out when they bunch up like in the pic. Feeding less will help control the population. @Redeye505

That's a great update.

I never owned a canister filter but I would try matching the old o-ring to one from home improvement store.

I have personally transported small fish in a five gallon bucket for short travel time. You could leave them in the 5 gallon as well. Some purchase battery powered air pumps but I think you will be fine without one. Don't fill either with too much water.

You will notice 2 keeping others away by chasing them from their chosen territory or area to spawn. Most cichlid species do what I've described.
